Question

please help

Answer 1

Do you know how to undo a square root?

Answer 2

Well, you can think of it like this:
\[\sqrt{x} = x^{1/2}\] It's another way to write a square root. In order to get x by itself, we'll have to square both sides.

Answer 3

\[(x^{1/2})^{2} = (-2)^{2}\]

The square root of 4 will give you both 2 and -2.

Yeshhh.
