What is the square root of using I?

The imaginary number i is defined as the square root of negative 1. We can write the square root of any negative number as a multiple of i. Consider the square root of –25. We use 5i and not −5i because the principal root of 25 is the positive root.

Why can’t we square root a negative number?

Negative numbers don’t have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can’t be written as the quotient of two integers.
