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

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

square root of a negative number is imaginary square root of negative 1 is defined as i square root of negative 144 is sqrt ((144)(-1)) = 12i

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.)

The square root of negative 37 is: ~6.0827 i

The square root of negative 168 is: ~12.9315 i

The square root of negative 40 is: 6.324555 i

The square root of a negative number is not real.

Negative 64 is the square root of an integer. The square root of -64 is not an integer.

Square roots of negative numbers are what are called imaginary numbers. The building block of imaginary numbers is the symbol i which is defined as the square root of negative 1. The square root of other negative numbers can be expressed using i. For example, the square root of negative sixteen is 4i, the square root of negative nine is 3i and so on.

The square root of four twenty-fifths, is two fifths, because of the fact that the square root of four is two and the square root of twenty-five is five.

-1,0,or 1 the negative square root of four is negative two and the square root of four is two

The square root of 100 is 10 but positive and a negative is a negative so it is negative 10

A negative square root is an imaginary number.

The negative square root of 324 is -18.

No, it is not even a real number. The square root of negative 5 is the square root of 5, times i.

The square root of negative 18 is an imaginary number.The square root of positive 18 is [ 3 sqrt(2) ].If the 18 is negative, then scientists and engineers indicate its square root as 3i sqrt(2) . The little ' i ' indicates the square root of negative one.

Treat it like a positive and add an i. Explanation: The square root of negative nine is equal to the square root of nine times negative one is equal to the square root of nine times the square root of negative one. The square root of negative one represented by an italic lower case i. The square root of negative nine is 3i. √-9 = √9 * -1 = √9 * √-1 = 3i

- (400^.5) = -(20) = -20 you just do the square root of the number, and attach the negative in front. and if you ever include the negative inside the square root, you'd have to deal with i, which is an imaginary number that signifies the square root of negative 1.

you can square a negative number but you can not square root a negative number

The principal square root is the non-negative square root.

There is no square root of a negative number. It would have to be a half negative, which is impossible.
