Examine whether the following numbers are rational or irrational:$ \sqrt{4} $

Given:

\( \sqrt{4} \)

To do:

We have to classify the given number as rational or irrational.

Solution:  

A rational number can be expressed in either terminating decimal or non-terminating recurring decimals and an irrational number is expressed in non-terminating non-recurring decimals.

Therefore,

$\sqrt{4}=2$

The decimal expansion of \( \sqrt{4} \) is terminating.

Therefore, \( \sqrt{4} \) is a rational number.
