you cant get the square root of a negative number. nothing times itself would equal a negative number. if you have √-25 then its not possible. If you have -√25 then you take the square root of 25 and make it negative, so then it would be -5
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.
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 ].
The square root of 625 is 25 because 25 x 25 = 625. 625 also has a negative root = -25.

Because the square root of -25 would be that number that, squared, would equal -25. No number, positive or negative, can result in a negative square. Since -25 is a negative number, no number, positive or negative, can be squared to equal -25.

The square root of 625 is 25 because 25 x 25 = 625. 625 also has a negative root = -25.
The square of 5 = 25 (= 5*5)The square root of 25 = 5

The square root of 25 has two solutions: SQRT(25) = + 5 and -5The square root of a number, by definition, should be positive. Hence, the square root of 25 is 5. The other square root is -5. However, strictly speaking, -5 is not the square root of 25, since it is not a positive number.* * * * *The exclusion of the negative square root is plain nonsense.
The principal root of a number is the positive real square root of the number - if it exists. Since -25 is negative, it does not have a real square root. Its square roots are the imaginary numbers +/-5i where i is the [imaginary] square root of -1. i is neither positive nor negative and so neither +5i nor -5i is a principal root.
A number will have both a positive and negative square root 5 x 5 = 25 and -5 x -5 = 25.
Any positive number has two square roots, a positive square root and its negative equivalent. This is because two negatives multiplied together equal a positive. In this instance, sqrt(625) = ±25 (that is, 25 and -25).
You cannot in real numbers because the square of any number, negative or positive, is positive. However, -25 does have a square root in complex numbers: it is + or - 5i where i is the imaginary square root of -1.
