227 229 271 317 349 You can use all the types of methods to try and get the answer, but you MUST use 1997, and keep it in that order no matter what. Please help, too hard 4 me...

What is the question?
Epicteatime
  • Epicteatime
You have to make those numbers by using 1997
Epicteatime
  • Epicteatime
you can't rearrange them, but you can use anything you want to make it the number. You can use powers, square roots, etc.
Epicteatime
  • Epicteatime
I can't get it at all, so I was wondering if anyone else could help me with this xD
imqwerty
  • imqwerty
interesting :)
Epicteatime
  • Epicteatime
Can't do it xD
Epicteatime
  • Epicteatime
Closest I got was 220
imqwerty
  • imqwerty
can we rearrange the number 1,9,9,7?
Epicteatime
  • Epicteatime
nope xD
Epicteatime
  • Epicteatime
it has to stay in that specific order
UnkleRhaukus
  • UnkleRhaukus
(1 + 9) x 9 x √7 = 238.1
Epicteatime
  • Epicteatime
SO CLOSE
UnkleRhaukus
  • UnkleRhaukus
this is hard, how did you get 220?
Epicteatime
  • Epicteatime
(19+9)+7^2
UnkleRhaukus
  • UnkleRhaukus
(1 + √9) x 9 x 7 = 252
UnkleRhaukus
  • UnkleRhaukus
(19 x 9) + 7^2 = 220
Epicteatime
  • Epicteatime
yep, thats what I did xD
Epicteatime
  • Epicteatime
closest thing I got xD
UnkleRhaukus
  • UnkleRhaukus
(1 x 9 x 9) + √7 = 214.3
Epicteatime
  • Epicteatime
:o
UnkleRhaukus
  • UnkleRhaukus
\[\sqrt{\sqrt{1\times 9^9\times7}}=228.2\]
Epicteatime
  • Epicteatime
wow, thats really close /:
Epicteatime
  • Epicteatime
So annoying... this stupid assignment.
anonymous
  • anonymous
can you use powers of numbers other than 1,9,9,7?
Epicteatime
  • Epicteatime
if you mean, can you square it or "double it" yes you can
Epicteatime
  • Epicteatime
but 1997 has to stay in place/ keep the same structure.
anonymous
  • anonymous
so you can use 1997 as many times as you want but it keeps that structure, like 1*9*9*7*1*9*9....etc?
Epicteatime
  • Epicteatime
oh... no thats not usable xD
anonymous
  • anonymous
so you can only use 1997 once then?
Epicteatime
  • Epicteatime
mhmm
anonymous
  • anonymous
(1 x 9 x 9) + √7 = 214.3
anonymous
  • anonymous
but wouldn't it be defeating the purpose if you use powers of 3 then? even tho you are multiplying it 3 times... your using a number not in that set..
anonymous
  • anonymous
probs over thinking it.
Epicteatime
  • Epicteatime
uhhh xD
Epicteatime
  • Epicteatime
I dunno xD Its hard just trying to do it the legit way xD
Jadedry
  • Jadedry
227 is a prime number, so I suppose the manipulation of the numbers you have should reflect that... I'm struggling quite a bit as well, but maybe you should work backwards? add 1, 9 or 7 to your target number and try to factorize it to get hints on how to create it..
Epicteatime
  • Epicteatime
:o thats a good idea, i'll try that now xD
Epicteatime
  • Epicteatime
I just got 226 :P
Epicteatime
  • Epicteatime
gg no re jade is a genius
imqwerty
  • imqwerty
can we do something like this- \[1 \times \sqrt{9},\sqrt[\infty]{9},7 =317\]?
Epicteatime
  • Epicteatime
yep
imqwerty
  • imqwerty
so 317 is done :)
Epicteatime
  • Epicteatime
:o thank you xD
Epicteatime
  • Epicteatime
But I don't get how it becomes 317 xD
imqwerty
  • imqwerty
\[1 \times \sqrt{9}=1 \times 3=3\]\[\sqrt[\infty]{9}=1\]\[7=7\] joining all :) 317
Epicteatime
  • Epicteatime
:o
Epicteatime
  • Epicteatime
thank you for your explanation xD
imqwerty
  • imqwerty
np (:
Epicteatime
  • Epicteatime
and thank you jade, i'll make sure to use your methods :D
Jadedry
  • Jadedry
@imqwerty You can join the numbers? don't you have to add or multiply?
Epicteatime
  • Epicteatime
OH
imqwerty
  • imqwerty
idk? @Epicteatime said yes so i did it :)
Epicteatime
  • Epicteatime
Yeah, you have to add them or multiply them to get the actual number, sorry Jade I didnt see how you got it xD
Epicteatime
  • Epicteatime
not jade, imqwerty
anonymous
  • anonymous
1×9√,9√∞,7=317
Jadedry
  • Jadedry
ah, so no joining then, that would have made it easier. :c
anonymous
  • anonymous
2^2 • 3 • 19 = 228 - (227 +1) 2 • 113 = 226 = (227-1) 22 • 5 • 11 = 220 = (227 - 7) 2 • 32 • 13 = 234 = (227 +7) 22 • 59 = 236 = (227 +9) 2 • 109 = 218 = (227 - 9)
Epicteatime
  • Epicteatime
yeah, it would have
Epicteatime
  • Epicteatime
lauren, thats not how you do it xD Thanks for your effort though :D
Jadedry
  • Jadedry
I'm sure this is actually a simple question at it's heart, I doubt we need fancy, doctorate level thesis' on how this could work. The numbers we have are 1 , 9 , 9 , 7 , they have to be dealt with in that order, but they can be subtracted and added to each other, as well as divided and multiplied. We can use any number we wish when "doubling" or calculating to the power, right @epicteatime ?
Jadedry
  • Jadedry
@Epicteatime I got ONE answer. \[1 * 9^{2.5} - 9 - 7 = 227 \]
Epicteatime
  • Epicteatime
sorry, I went to eat dinner xD Im back now tho :D
Epicteatime
  • Epicteatime
and thank you for answering one xD
Epicteatime
  • Epicteatime
sadly there's still like, 4 :P
Jadedry
  • Jadedry
@Epicteatime Hope you enjoyed dinner haha, I know, but once one goes down, surely the rest should be easier? XD
Epicteatime
  • Epicteatime
maybe, maybe
Epicteatime
  • Epicteatime
xD
Epicteatime
  • Epicteatime
which one are you doing jade?
Jadedry
  • Jadedry
I'm trying to do the second one now, it's only a difference of 2 so...
Epicteatime
  • Epicteatime
alright, i'll do 271 then :D
Epicteatime
  • Epicteatime
holy crap...
Epicteatime
  • Epicteatime
I Just got 271
Epicteatime
  • Epicteatime
but I still need to do something with 7 xD
Jadedry
  • Jadedry
So, I need to subtract 14 from \[9^{2.5}\] in order to get 229. How can I make 14? --- Also, congrats! I'm sure you can turn the 7 into a 0 somehow...
FireKat97
  • FireKat97
so which ones do you have left? haha
Epicteatime
  • Epicteatime
229 271 317 349
Epicteatime
  • Epicteatime

FireKat97
  • FireKat97
ahh okiee
Epicteatime
  • Epicteatime
yush :3
Epicteatime
  • Epicteatime
I GOT 271!!!!
Epicteatime
  • Epicteatime
oh wait...
Epicteatime
  • Epicteatime
1997-99-1/7
Epicteatime
  • Epicteatime
uhh
Epicteatime
  • Epicteatime
hmmm....
Epicteatime
  • Epicteatime
1-99/7=271? xD
FireKat97
  • FireKat97
can we use the numbers 1, 9, 9 and 7 as many times as we'd like?
Epicteatime
  • Epicteatime
nope xD
Epicteatime
  • Epicteatime
sadly xD
FireKat97
  • FireKat97
damn ahahha
FireKat97
  • FireKat97
but can we rearrange stuff to make like 99 and 17 and stuff?
Epicteatime
  • Epicteatime
99 yes, 17 no xD
Epicteatime
  • Epicteatime
you have to keep 1997 in that order
FireKat97
  • FireKat97
OH i think I'm finally clear on the rules lololol
Epicteatime
  • Epicteatime
lol xD well try your best :D
FireKat97
  • FireKat97
so slow xD haha, okay
Epicteatime
  • Epicteatime
damn
Epicteatime
  • Epicteatime
I got 318
Epicteatime
  • Epicteatime
.7
Epicteatime
  • Epicteatime
so basically 319 xD
Jadedry
  • Jadedry
you got 317?
Jadedry
  • Jadedry
can't you subtract 7^0 to get 317?
Epicteatime
  • Epicteatime
:o
Epicteatime
  • Epicteatime
wait a sec :3
Epicteatime
  • Epicteatime
1 x 9^2.6+9+7
Epicteatime
  • Epicteatime
just putting that there
Epicteatime
  • Epicteatime
I did what you told me jade, and I got 311 xD
Jadedry
  • Jadedry
whoops haha
FireKat97
  • FireKat97
we can't do 199 + (19 x (9 - 7)) - (7 + 1) = 229 can we? :/
Jadedry
  • Jadedry
don't think so firekat :c
Epicteatime
  • Epicteatime
ah no xD sorry m80 :P
FireKat97
  • FireKat97
hahah damn
FireKat97
  • FireKat97
btw what year is this? this is torture lol I'd hate getting an assignment like this
Epicteatime
  • Epicteatime
year 10 xD
FireKat97
  • FireKat97
omg seriously, our assignments were so easy in comparison
FireKat97
  • FireKat97
hahahaha we'd get like quadratics 90% of the time
Jadedry
  • Jadedry
Considering I just started year 11 it is kind of embarrassing I can't solve this lmao
FireKat97
  • FireKat97
lol Im a first year and can't solve it so :$
Jadedry
  • Jadedry
but we need to carry on, we can do this!
Epicteatime
  • Epicteatime
YES
Epicteatime
  • Epicteatime
BELIEVE IN YOUR DREAMS!
FireKat97
  • FireKat97
HAHAHA
Epicteatime
  • Epicteatime
xD
Epicteatime
  • Epicteatime
I GOT IT
Epicteatime
  • Epicteatime
229!
FireKat97
  • FireKat97
yayayayyayay!!
Epicteatime
  • Epicteatime
1*(99+7^2.5)
FireKat97
  • FireKat97
good job!
Epicteatime
  • Epicteatime
that SHOULD work
Epicteatime
  • Epicteatime
you round it so you get 229
FireKat97
  • FireKat97
but how did you get 2.5?
Jadedry
  • Jadedry
So you're allowed to combine numbers?
Epicteatime
  • Epicteatime
Yeah, just keep the order
Epicteatime
  • Epicteatime
2.5? its the power
Jadedry
  • Jadedry
why did i not know this also are you sure you can just round it off?
FireKat97
  • FireKat97
ohh we can use any power?
Epicteatime
  • Epicteatime
pretty sure.
Epicteatime
  • Epicteatime
and yes, you can xD
FireKat97
  • FireKat97
ahhh okayyyy
Epicteatime
  • Epicteatime
you just can't change the number, or change its position
FireKat97
  • FireKat97
ah oka cool
Epicteatime
  • Epicteatime
:3
Jadedry
  • Jadedry
\[1 * (9 - \sqrt9) + 7 ^3 = 349\]
Epicteatime
  • Epicteatime
:o
Epicteatime
  • Epicteatime
NICE :D
Jadedry
  • Jadedry
YAS
FireKat97
  • FireKat97
woww niceee
Jadedry
  • Jadedry
so 229 271 317 left?
Epicteatime
  • Epicteatime
I got 229
Jadedry
  • Jadedry
ah okay
Epicteatime
  • Epicteatime
we only got 2 more left
Epicteatime
  • Epicteatime
317 and 349
Jadedry
  • Jadedry
I got 349 : o
Epicteatime
  • Epicteatime
yep :3
Epicteatime
  • Epicteatime
MVP
Epicteatime
  • Epicteatime
xD
Jadedry
  • Jadedry
so 271 + 317 ?
Epicteatime
  • Epicteatime
?
FireKat97
  • FireKat97
so if we can use any powers and round off, would \[1 \times 9^{5/2} + 9^{3/2} \times 7^{0.026}\] work? cus it gives 271.401..
FireKat97
  • FireKat97
so if we can use any powers and round off, would \[1 \times 9^{5/2} + 9^{3/2} \times 7^{0.026}\] work? cus it gives 271.401..
Epicteatime
  • Epicteatime
uhhh... yeah I guess xD
Jadedry
  • Jadedry
You said we have two left, you solved 229 , and I solved 227 + 349 so the other two are 271 and 317
Epicteatime
  • Epicteatime
ohh thats what you meant xD yes, thats what we have left :D
Jadedry
  • Jadedry
Very close FireKat! Although I'm wary of decimals, if 2 don't have decimals should others?
Epicteatime
  • Epicteatime
actually its 349 and 317
FireKat97
  • FireKat97
oh
Epicteatime
  • Epicteatime
wait no
Jadedry
  • Jadedry
\[1 * (9 - \sqrt9) + 7^3 \] = 349 \[1 * 9^{2.5} - 9 - 7\] = 227
Epicteatime
  • Epicteatime
271 and 317
Jadedry
  • Jadedry
yes
Epicteatime
  • Epicteatime
is what we have left.
Epicteatime
  • Epicteatime
i got 319 again xD
Jadedry
  • Jadedry
What is your equation?
Epicteatime
  • Epicteatime
1x(9^2.5+9)+7
Jadedry
  • Jadedry
Isn't that 259?
Epicteatime
  • Epicteatime
no idea xD
Jadedry
  • Jadedry
9^2.5 + 9 + 7 = 259
Epicteatime
  • Epicteatime
damn, got 270, and gg :D
Epicteatime
  • Epicteatime
1+(9.9^3.29)/7
Epicteatime
  • Epicteatime
oh wait I got it
Epicteatime
  • Epicteatime
1+(9.9^3.291)/7 :P
Epicteatime
  • Epicteatime
271.1
Epicteatime
  • Epicteatime
now we only have 317
Jadedry
  • Jadedry
very close
Jadedry
  • Jadedry
Unfortunately I can't stay any more, I have a lot of work myself. :c Please message me with your results. ;u;
Epicteatime
  • Epicteatime
lol alright xD Thanks a lot for your help fwendo :D
Epicteatime
