There is no square root of negative 8, negative numbers can never be square rooted since no two of the same number can go into a negative number, for example 16's square root is 4 and -4 since 4x4=16 and -4x-4=16, but -16 doesn't have a square root since -4 just turns into a positive when multiplied to itself.
