Find the square root of x2

The square root of any number is equal to a number, which when squared gives the original number. Let us assume that m is a positive integer, such that √(m.m) = √(m2) = m.

The square root symbol is usually denoted as ‘√’. It is called a radical symbol. To represent a number ‘x’ as a square root using this symbol can be written as:
‘ √x ‘where x is the number. The number under the radical symbol is called the radicand.
