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

You have to make those numbers by using 1997

- 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

I can't get it at all, so I was wondering if anyone else could help me with this xD

- imqwerty

interesting :)

- Epicteatime

Can't do it xD

- Epicteatime

Closest I got was 220

- imqwerty

can we rearrange the number 1,9,9,7?

- Epicteatime

nope xD

- Epicteatime

it has to stay in that specific order

- UnkleRhaukus

(1 + 9) x 9 x √7 = 238.1

- Epicteatime

SO CLOSE

- UnkleRhaukus

this is hard, how did you get 220?

- Epicteatime

(19+9)+7^2

- UnkleRhaukus

(1 + √9) x 9 x 7 = 252

- UnkleRhaukus

(19 x 9) + 7^2 = 220

- Epicteatime

yep, thats what I did xD

- Epicteatime

closest thing I got xD

- UnkleRhaukus

(1 x 9 x 9) + √7 = 214.3

- Epicteatime

:o

- UnkleRhaukus

\[\sqrt{\sqrt{1\times 9^9\times7}}=228.2\]

- Epicteatime

wow, thats really close /:

- Epicteatime

So annoying... this stupid assignment.

- anonymous

can you use powers of numbers other than 1,9,9,7?

- Epicteatime

if you mean, can you square it or "double it" yes you can

- Epicteatime

but 1997 has to stay in place/ keep the same structure.

- 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

oh... no thats not usable xD

- anonymous

so you can only use 1997 once then?

- Epicteatime

mhmm

- anonymous

(1 x 9 x 9) + √7 = 214.3

- 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

probs over thinking it.

- Epicteatime

uhhh xD

- Epicteatime

I dunno xD Its hard just trying to do it the legit way xD

- 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

:o thats a good idea, i'll try that now xD

- Epicteatime

I just got 226 :P

- Epicteatime

gg no re jade is a genius

- imqwerty

can we do something like this-
\[1 \times \sqrt{9},\sqrt[\infty]{9},7 =317\]?

- Epicteatime

yep

- imqwerty

so 317 is done :)

- Epicteatime

:o thank you xD

- Epicteatime

But I don't get how it becomes 317 xD

- imqwerty

\[1 \times \sqrt{9}=1 \times 3=3\]\[\sqrt[\infty]{9}=1\]\[7=7\]
joining all :)
317

- Epicteatime

:o

- Epicteatime

thank you for your explanation xD

- imqwerty

np (:

- Epicteatime

and thank you jade, i'll make sure to use your methods :D

- Jadedry

@imqwerty
You can join the numbers? don't you have to add or multiply?

- Epicteatime

OH

- imqwerty

idk? @Epicteatime said yes so i did it :)

- 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

not jade, imqwerty

- anonymous

1×9√,9√∞,7=317

- Jadedry

ah, so no joining then, that would have made it easier. :c

- 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

yeah, it would have

- Epicteatime

lauren, thats not how you do it xD Thanks for your effort though :D

- 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

@Epicteatime
I got ONE answer.
\[1 * 9^{2.5} - 9 - 7 = 227 \]

- Epicteatime

sorry, I went to eat dinner xD Im back now tho :D

- Epicteatime

and thank you for answering one xD

- Epicteatime

sadly there's still like, 4 :P

- Jadedry

@Epicteatime
Hope you enjoyed dinner haha,
I know, but once one goes down, surely the rest should be easier? XD

- Epicteatime

maybe, maybe

- Epicteatime

xD

- Epicteatime

which one are you doing jade?

- Jadedry

I'm trying to do the second one now, it's only a difference of 2 so...

- Epicteatime

alright, i'll do 271 then :D

- Epicteatime

holy crap...

- Epicteatime

I Just got 271

- Epicteatime

but I still need to do something with 7 xD

- 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

so which ones do you have left? haha

- Epicteatime

229
271
317
349

- Epicteatime

those :3

- FireKat97

ahh okiee

- Epicteatime

yush :3

- Epicteatime

I GOT 271!!!!

- Epicteatime

oh wait...

- Epicteatime

1997-99-1/7

- Epicteatime

uhh

- Epicteatime

hmmm....

- Epicteatime

1-99/7=271? xD

- FireKat97

can we use the numbers 1, 9, 9 and 7 as many times as we'd like?

- Epicteatime

nope xD

- Epicteatime

sadly xD

- FireKat97

damn ahahha

- FireKat97

but can we rearrange stuff to make like 99 and 17 and stuff?

- Epicteatime

99 yes, 17 no xD

- Epicteatime

you have to keep 1997 in that order

- FireKat97

OH i think I'm finally clear on the rules lololol

- Epicteatime

lol xD well try your best :D

- FireKat97

so slow xD haha, okay

- Epicteatime

damn

- Epicteatime

I got 318

- Epicteatime

.7

- Epicteatime

so basically 319 xD

- Jadedry

you got 317?

- Jadedry

can't you subtract 7^0 to get 317?

- Epicteatime

:o

- Epicteatime

wait a sec :3

- Epicteatime

1 x 9^2.6+9+7

- Epicteatime

just putting that there

- Epicteatime

I did what you told me jade, and I got 311 xD

- Jadedry

whoops haha

- FireKat97

we can't do 199 + (19 x (9 - 7)) - (7 + 1) = 229 can we? :/

- Jadedry

don't think so firekat :c

- Epicteatime

ah no xD sorry m80 :P

- FireKat97

hahah damn

- FireKat97

btw what year is this? this is torture lol I'd hate getting an assignment like this

- Epicteatime

year 10 xD

- FireKat97

omg seriously, our assignments were so easy in comparison

- FireKat97

hahahaha we'd get like quadratics 90% of the time

- Jadedry

Considering I just started year 11 it is kind of embarrassing I can't solve this lmao

- FireKat97

lol Im a first year and can't solve it so :$

- Jadedry

but we need to carry on, we can do this!

- Epicteatime

YES

- Epicteatime

BELIEVE IN YOUR DREAMS!

- FireKat97

HAHAHA

- Epicteatime

xD

- Epicteatime

I GOT IT

- Epicteatime

229!

- FireKat97

yayayayyayay!!

- Epicteatime

1*(99+7^2.5)

- FireKat97

good job!

- Epicteatime

that SHOULD work

- Epicteatime

you round it so you get 229

- FireKat97

but how did you get 2.5?

- Jadedry

So you're allowed to combine numbers?

- Epicteatime

Yeah, just keep the order

- Epicteatime

2.5? its the power

- Jadedry

why did i not know this
also are you sure you can just round it off?

- FireKat97

ohh we can use any power?

- Epicteatime

pretty sure.

- Epicteatime

and yes, you can xD

- FireKat97

ahhh okayyyy

- Epicteatime

you just can't change the number, or change its position

- FireKat97

ah oka cool

- Epicteatime

:3

- Jadedry

\[1 * (9 - \sqrt9) + 7 ^3 = 349\]

- Epicteatime

:o

- Epicteatime

NICE :D

- Jadedry

YAS

- FireKat97

woww niceee

- Jadedry

so
229
271
317
left?

- Epicteatime

I got 229

- Jadedry

ah okay

- Epicteatime

we only got 2 more left

- Epicteatime

317 and 349

- Jadedry

I got 349 : o

- Epicteatime

yep :3

- Epicteatime

MVP

- Epicteatime

xD

- Jadedry

so 271 + 317 ?

- Epicteatime

?

- 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

- Epicteatime

uhhh... yeah I guess xD

- Jadedry

You said we have two left,
you solved 229 , and I solved 227 + 349 so the other two are 271 and 317

- Epicteatime

ohh thats what you meant xD yes, thats what we have left :D

- Jadedry

Very close FireKat!
Although I'm wary of decimals, if 2 don't have decimals should others?

- Epicteatime

actually its 349 and 317

- FireKat97

oh

- Epicteatime

wait no

- Jadedry

\[1 * (9 - \sqrt9) + 7^3 \] = 349
\[1 * 9^{2.5} - 9 - 7\] = 227

- Epicteatime

271 and 317

- Jadedry

yes

- Epicteatime

is what we have left.

- Epicteatime

i got 319 again xD

- Jadedry

What is your equation?

- Epicteatime

1x(9^2.5+9)+7

- Jadedry

Isn't that 259?

- Epicteatime

no idea xD

- Jadedry

9^2.5 + 9 + 7 = 259

- Epicteatime

damn, got 270, and gg :D

- Epicteatime

1+(9.9^3.29)/7

- Epicteatime

oh wait I got it

- Epicteatime

1+(9.9^3.291)/7 :P

- Epicteatime

271.1

- Epicteatime

now we only have 317

- Jadedry

very close

- Jadedry

Unfortunately I can't stay any more, I have a lot of work myself. :c
Please message me with your results. ;u;

- Epicteatime

lol alright xD Thanks a lot for your help fwendo :D
