The square root of a number is a number, when multiplied by itself, equals a desired value.
See below for proof
The square root of a number n, is represented as:
[tex]\mathbf{\sqrt{n}}[/tex]
This can be rewritten as:
[tex]\mathbf{\sqrt{n} = \sqrt[2]{n}}[/tex]
According to law of indices
[tex]\mathbf{\sqrt[x]{m} = x^\frac{1}{m}}[/tex]
Using the above rule, we have:
[tex]\mathbf{\sqrt{n} = n^\frac{1}{2}}[/tex]
Hence, the square root of a number is the same as the number to the power of 1/2
