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 # 6 and the # -5 are 30 less than their square root. 6^2 = 36 > 36 - 6 = 30 -5^2 = 25 (because a negative times a negative = a positive)

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.

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

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 625 is 25 because 25 x 25 = 625. 625 also has a negative root = -25.

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.

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.

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 # 6 and the # -5 are 30 less than their square root. 6^2 = 36 > 36 - 6 = 30 -5^2 = 25 (because a negative times a negative = a positive)
