Any positive number x has two square roots: one positive and one negative. For example, +3 and -3 are both square roots of 9.

Using a brilliant leap of imagination, mathematicians decided to call the first of these the positive root!

Why cant you evaluate the square root of negative twenty five using real numbers?

using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number

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.
