### What is the square root of negative twenty?

Because the Square Root of negative 1 = i (The imaginary square
root of negative 1.) and where if the square root of one number and
of another number are multiplied together, the answer is equal to
the square root of the two numbers combined. (Square root of 8
times the square root of 5 equals the square root of 40.)
So...
√(-20)
=√20×√(-1)
=√4×√5×i
=2i(√5)
The answer is 2i times the square root of 5.
square root (-20) = square root (-1) x square root (20)
square root (-20) = i x 4.47213595
square root (-20) = 4.47213595 i
