In mathematics, a square root of a number x is a number y such that y 2 = x ; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16 because 4 2 = 2 = 16. Every nonnegative real number x has a unique nonnegative square root, called the principal square root or simply the square root, which is denoted by x, where the symbol " " is called the radical sign or radix. For example, to express the fact that the principal square root of 9 is 3, we write 9 = 3. The
