The square root of a positive is positive. Because sqrt(x)= x^(1/2), then sqrt( sqrt(x) ) = x^(1/4). The square root of a negative 1 is i.

Take, for example, 81. The square root of 81 is 9, the square root of 9 is 3. You could keep square-rooting ad infinitum. Logically, you cannot square root a negative number. The closest you could come to the square root of -9 would be 3 times (-3), which isn't a true square root. Any negative number squared will always end up a positive number. (-3)^2 equals 9.

maybe if you take a square potato and then carve out an even smaller square potato and put the first potato back together you will have your solution. Square potatoes come from Square-ville located west of the Mississippi.
