WitrynaDefinition of square root. 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 y. For example, 5 is the square root of 25 because 5 2 = 5•5 = 25, -5 is square root of 25 because (-5) 2 = (-5)• (-5) = 25. When writing math, people often use sqrt (x) to mean the square root of x. WitrynaA square root can be negative – for example, when we take the opposite of the principal square root of a positive number.
