What is the real number root of -25?
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.
Is the square root of 8 over 25 rational irrational or a real number?
The square root of 8 over 25 is irrational, and real.
Is the square root of negative 25 a rational number?
The square root of -25 is not a real number, as it involves taking the square root of a negative number which results in an imaginary number. In this case, the square root of -25 is 5i, where i represents the imaginary unit. Since rational numbers are a subset of real numbers, the square root of -25, being an imaginary number, is not a rational number.
Why does the square root of -25 have no real solution?
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.
What is the principal root of -25?
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.
Can the square root of 25 be a real number?
the square root of 25 is 5
Is the root of 25 a real number?
Yes. The square root of 25 is 5, which is a real number.
What is the real number root of -25?

Is the square root of 8 over 25 rational irrational or a real number?
The square root of 8 over 25 is irrational, and real.
Why does the square root of 25 not have a real solution?
You can't take the square root of a negative number. The square root of -25 is 5i. It's an imaginary number.
Is radical 25 a real number?
If by "radical" you mean "square root of", then yes. Both square roots of 25 are real numbers.
Why does the square root of -25 have no real solution?
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.
What is the principal root of -25?

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.
What is the square root of a positive?
The square root of a positive number results in a positive number. For example, the square root of 25 is 5. * * * * * Not true! There are two real square roots for every positive number: one positive and one negative. -5 is as much a square root of 25 as +5 is. However, the positive root is the principal root and so is often presented as the only root.
Why cant you evaluate square root -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.
Is the square root of 25 an irrational or rational number?
The square root of 25 is 5, which is a rational number.
What are the square root number for 25?
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.
