Question

Not sure how to solve this:
in comment.

Answer 1

\[\sqrt{x+5}=8\]

Answer 2

Well you wanna undo the square root so you can solve for x, so to do that you would square both sides, right?

Answer 3

So it would be:
\[x^2+25 = 64\]

Answer 4

No, when you square a square root, all it does it get rid of the square root.
So:
x+5=64

Answer 5

Ohhh, okay. Didn't realize that. So x=59?

Answer 6

Yep.

Answer 7

Okay, do you think you could help me with one more? So I understand how to do it?
\[\sqrt{8x+5}= 3\sqrt{x}\]

Answer 8

Yeah, im guessing you do the same thing, square both sides and you get:
8x+5=9x
5=x
