If x is a positive integer, is [(x)^(1/2)]^(1/2) ?
(1) x is the square of an integer.
(2) \sqrt{x} is the square of an integer.
I agree with the OA. However, I have a doubt with (2):
\sqrt{x} = i^2 , being i an integer.
Should we unsquare or use an additional square root on i? Is there a difference? I know that the square root only provide the positive root of the number.
Thanks!![]()
