When a number is perfect square then its principal root?
Lesson Summary Every positive real number has a positive and a negative square root; the positive root is called the principal root. When the square root of a number is a whole number, meaning no non-zero digits to the right of the decimal, then it is known as a perfect square.
How do we find a perfect square?
