$\bold{Answer:}$

$\huge\boxed{\fcolorbox{red}{white}{ irrational number }}$

$\bold{Step-by-step-explaination:}$

we have,

$\sqrt{45}$

$= \sqrt{9 \times 5}$

$= \sqrt{ {(3)}^{2} \times 5}$

$= 3 \sqrt{5}$

since $\sqrt{5}$ is an irrational number.

Therefore, $3 \sqrt{5}$ is also an irrational number.
