Formula

The square root of a non-negative number a is the value x such that:

x² = a  ⇔  √a = x  (for x ≥ 0)

Every positive number has two square roots: a positive one (the principal root returned by this calculator) and a negative one. For example, √25 = 5 and also -5, since (-5)² = 25.

The square root of a negative number is not a real number — it is an imaginary number written as i√|a|.

What is a square root?

A square root of a number 'a' is a number x such that x² = a — a number whose square is a. For example, 219 is the square root of 47961 because 219² = 219 · 219 = 47961; and -219 is also a square root of 47961 because (-219)² = (-219) · (-219) = 47961.
