im having trouble with this i will fan and medal for help

  • sloppycanada
Alright, this is actually pretty simple. Well simple-ish.
anonymous
  • anonymous
ok
sloppycanada
  • sloppycanada
Start with A. |dw:1446792532053:dw|
sloppycanada
  • sloppycanada
Now, do you have a calculator?
anonymous
  • anonymous
ok
anonymous
  • anonymous
yep have one on my computer
sloppycanada
  • sloppycanada
Alright, so the first thing you want to do is simplify both sides. So divide 529 by 2.
sloppycanada
  • sloppycanada
And then the square root of 529.
anonymous
  • anonymous
ok
anonymous
  • anonymous
264.5
sloppycanada
  • sloppycanada
|dw:1446792612656:dw| Now obviously these two are NOT the same.
anonymous
  • anonymous
ohhhh nvm
sloppycanada
  • sloppycanada
So now we can cross of A as an answer since we know that it is not equal.
anonymous
  • anonymous
ok
sloppycanada
  • sloppycanada
The next one is |dw:1446792757101:dw|
anonymous
  • anonymous
ok what do i do now?
sloppycanada
  • sloppycanada
Obviously, if the first one 529/2 was wrong, multiplying it will not make it right.
anonymous
  • anonymous
ok
anonymous
  • anonymous
i went ahead and gave you a medal for helping me as soon as you could
sloppycanada
  • sloppycanada
|dw:1446792810879:dw| And since when you square root something, you're making the number smaller, we can eliminate B from our answer pool.
sloppycanada
  • sloppycanada
Do you understand so far? And thank you.
anonymous
  • anonymous
yea im getting it
anonymous
  • anonymous
well i should say im understanding it (and your welcome)
sloppycanada
  • sloppycanada
Great! Moving on to C - do you know what the square root of 529 is?
anonymous
  • anonymous
no
sloppycanada
  • sloppycanada
That's why we have a calculator. So go ahead and plug in the square root of 529
anonymous
  • anonymous
so i divide right?
sloppycanada
  • sloppycanada
No. Look for a simple that looks like \[\sqrt{}\]
anonymous
  • anonymous
im on a cromebook i dont have one of those
anonymous
  • anonymous
wait be righr back
sloppycanada

anonymous
  • anonymous
nvm i found one on google
anonymous
  • anonymous
23
sloppycanada
  • sloppycanada
Alrighty, using whatever method you want to, find me the square root of 529, I recommend mathaway, as it is a very helpful site.
anonymous
  • anonymous
ok
anonymous
  • anonymous
the square root is 23 right
sloppycanada
  • sloppycanada
So now that you know the left side of C, you can figure out the rest. |dw:1446793343547:dw|
anonymous
  • anonymous
k
sloppycanada
  • sloppycanada
So just a note, when you have |dw:1446793426875:dw| they want you to multiply something by itself. So in our case, 23 x 23.
anonymous
  • anonymous
ok
FaireGaming
  • FaireGaming
23 To the 2nd power is the same as the start :P
sloppycanada
  • sloppycanada
We don't want to bother doing that in this case, since we also have a square root. So yeah, 23.
sloppycanada
  • sloppycanada
That means that the correct answer to your problem is C. Since both sides are equal. 23 = 23 \[\sqrt{529}=\sqrt{23^2}\]
anonymous
  • anonymous
ok thanks a lot
anonymous
  • anonymous
@sloppycanada your a lifesaver
sloppycanada
  • sloppycanada
Haha thanks, I hope you understand this type of problem a bit better now.
anonymous
  • anonymous
i do now by a whole lot
anonymous
  • anonymous
hey do you think maybe you could help me a lot more in the future
anonymous
  • anonymous
at least i got this question right
sloppycanada
  • sloppycanada
Haha, if you were concerned with the other questions, I could've helped you out.
anonymous
  • anonymous
WHY AM I NOT SMART :(
anonymous
  • anonymous
oh :3 again im not smart the only problem is is ive failed this test 3 time and this question was the one bugging me
anonymous
  • anonymous
ok im going to close this lesson now @sloppycanada
sloppycanada
  • sloppycanada
Okay, sounds good.
