$\sf{Answer :-} \:$

Definition :-

The square root of any number is equal to a number, which when squared gives the original number.

Let us say m is a positive integer, such that

$\sf{ \sqrt{m.m} = \sqrt{ {(m}^{2} )} } = m$

Note: The square root of a negative number represents a complex number.

Symbol :-

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. For example, the square root of 6 is also represented as radical of 6. Both represent the same value.

Formula :-

The formula to find the square root is:

y = √a

Since, y.y = y2 = a; where ‘a’ is the square of a number ‘y’.
