Square root of a number is a value, which on multiplication by itself, gives the original number. The square root is an inverse method of squaring a number. Hence, squares and square roots are related concepts. Suppose x is the square root of y, then it is represented as x=√y, or we can express the same equation as x2 = y. Here, ‘√’ is the radical symbol used to represent the root of numbers. The positive number, when multiplied by itself, represents the square of the number. The ... Square roots mean you multiply the same number twice to equal another number. Square root of a number is essentially the value that, when multiplied by itself, yields the original number. This concept is denoted by the radical symbol (√) and is expressed as √n or n1/2, where 'n' is a positive number.
