Definition and Notation. The square root of a number a a, denoted \sqrt {a} a, is the number b b such that. b^ {2} = a\text { and }b\ge 0. b2 = a and b ≥ 0. The square root symbol " \sqrt {\ } " is also sometimes called a radical. The number or expression underneath the top line of the square root symbol is called the radicand.
Oct 9, 2018 · The square root of a number is another number that when multiplied by itself equals this number. For example, the square root of 25 is 5 because 5 × 5 = 25. Instead of writing ‘find the square root of’ in front of each number, it is quicker to use the square root sign. The mathematical symbol for finding the square root is √.
