Question

State True or False.

$\sqrt{4}$ is an irrational number.

• A. True
• B. False

Answer 1

The correct option is B False

We know that, a rational number is a real number that can be represented in the form of $\frac{p}{q}$ where both $p$ and $q$ are co-prime.

Given number is $\sqrt{4}$

$\Rightarrow \sqrt{4}=2$

We can write $2$ as $\frac{2}{1}$ where both $2$ and $1$ are co-prime.

So, $\sqrt{4}$ is a rational number.

Hence, the given statement is false.
