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

5

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

There is no answer - 5 * -5 is 25 as a negative times a negative is a positive and - - 5 * 5 is - 25 but you cannot do this inversely if you put square root - 25 it says undefined

It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).

- (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.

The square root of any negative number is equal to the square root of its absolute value followed by i - an imaginary number representing the square root of minus one. Therefore, such that sqrt(25) = 5, sqrt(-25) = 5i.

first of all the square root of any negative number is technically impossible, but in certain maths it can be accepted in terms of imaginary number, i. so to answer your question it is about 2.236067977i

A number will have both a positive and negative square root 5 x 5 = 25 and -5 x -5 = 25.

In increasing order, they arenegative 31 over 6negative square root 26negative 5negative 5 over 6

It is. (-5) is a perfectly good square root of 25.Every number has two square roots. The two square roots of 25 are [ +5 ] and [ -5 ].

sqrt(-5) + sqrt(-20) = sqrt(-5) + sqrt(4)*sqrt(-5)= sqrt(-5) + 2*sqrt(-5) = 3*sqrt(-5)3*sqrt(5)*i or 6.7082*iwhere i is the imaginary square root of -1.
