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

five
Why cant you evaluate the square root of negative twenty five using real numbers?
using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number
How do you get the square root of negative 144?

How do you do a square root of a negative number that is not a perfect square?
The square root of a negative number is not real.
What is the square root of a negative number plus the square root of a negative number?
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
