Answer 2

Answer

That's an quite easy question.But here I will explain it more deeply.

Let us first understand what properties rational number carries.Through this we can easily claim the numbers which are rational.

Rational number:

ᐅ It can be expressed in form of $\rm \frac { p } { q }$ where $\rm q \neq 0$

ᐅ It has decimal expansion which terminates( stop at a position)

ᐅ Numbers having Non terminating repeating decimal expansions are also rational numbers.

Now, coming to your question

$\implies \rm \sqrt{49}$

It can be simplified as $\rm \sqrt{7^2}$

Which means we got our answer as ' 7 ' which could be expressed in form of $\rm \frac { p } { q }$ as $\rm \frac { 7 } { 1 }$ where $\rm q \neq 0$

Hence $\rm \sqrt{49}$ is a rational number.
