A square root is the opposite of a square (exponent of 2).

Explanation:

For example:

sqrt121 = 11*11;11^2√121=11⋅11;112

Notice that in the answer (11*11) both numbers are the same.

sqrt -1√−1 is a bit more complicated, with the answer being ii as no two identical numbers can be multiplied together to get -1.

Hope this helps.
