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

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.
