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.

You can't take the square root of a negative number. The square root of -25 is 5i. It's an imaginary number.

the square root of 25 is 5

It DOES have two real solutions: -5 and +5 so the question is misguided.

There is no real number [square] root of a negative number. There is a real cube root and a real fiftth root etc, but root, by itself, implies square root.

Yes. The square root of 25 is 5, which is a real number.

The square root of 8 over 25 is irrational, and real.

+25.

no. is not a real number

5 is the square root of 25 25 is the square root of 625 625 is the square of 25 25 is the square of 5

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.

If by "radical" you mean "square root of", then yes. Both square roots of 25 are real numbers.

Square root of 25 = 5

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.

The square root of 25 is 5.

The square root of 25 is 5 ... rational.

41

441 square root

The square root of 36 is 20% more than the square root of 25.

You mean square root of 25? (Answer: 5)

Square root of 25 = 251/2 = 5, which is an integer. So the square root of 25 is integer.

The square root of 25 is +/- 5 since 52 = 25 and (-5)2 = 255

The square root of 25 is 5. The square root of 9 is 3. The square root of 259 is 16.1

Neither. It is not a real number but a complex number. Sqrt(-25) = i5 where i is the imaginary number which is the square root of -1.

The square root of 25 is 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.
