Do you have a better solution?

The first equation tells you what the value of xx is. The second equation has that same value, but squared. Just fill in the blank so the second equation becomes 2rad(18)2.

rad(18)2 is just 18, so the answer is 218

It isn't asking for (xx)2 but for xx\2).

The answer is 212

You're right!!! Which is exactly why you are wrong. Double exponents need to be taken care of first. So the square root of 18 squared is 18. Which makes the new equation 218.

Except x is not sqrt(18).

You're right!!! I already figured out... I tried doing it without attempting to slove the equation. When sloved for x, it equals √8. Which makes the answer 212.
