Square root. In mathematics, a square root of a number a is a number y such that yÂ² = a, or, in other words, a number y whose square is a. For example, 4 and â4 are square roots of 16 because 4Â² = Â² = 16. Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by, where â is called the radical sign or radix.
