Detailed Solution

Given expression is

\sqrt{7} .

Rational numbers are those numbers which can be expressed in the form

\frac{p}{q}

, where p and
are integers and

q \neq 0

.
Numbers which are not rational numbers are called irrational numbers.
Since,

\sqrt{7}

cannot be written in

\frac{p}{q}

, where

p

and

q

are integers and

q \neq 0

So, it is an irrational number.
So, the correct option is 2.
