What is the square root of zero?

"0" And if you think about it, zero times zero is still zero. Zero times anything is zero, so this doesn't have an exception when you do the reverse to find the square root.
The square root of a number (n) is a number that when multiplied by itself (squared) results in the original number (n). Therefore, the square root of 0 must be 0 because 0 x 0 = 0.
