The square root of 121 is 11i, because negative numbers usually cannot have a square root or a large square root. I represent the imaginary unit. Every number that multiplies by itself must be a positive number, so the square root of a negative number cannot be.
The square of any positive or negative number is positive and the square of 0 is 0. In this case, no negative number has a real square root.

Square (121) = square (121) * square (1) = 11 * i.
