Yes, $$\sqrt{0}=0$$, since $$0^2=0$$.

Hope it's clear.

Hope it's clear.

What about square root of -1? I have never seen square root of -1 in GMAT and assume that such case is not tested?

All numbers on the GMAT are real numbers, so $$\sqrt{negative}$$, which is an imaginary number, is not defined for the GMAT.
