Yes square root of 18 divided by square root of 2 is equal to 2. Which is clearly rational number. Irrational numbers actually have these decisions hidden at the infinitesimal decimal place.Nov

Answer 2

Answer: Rational Number

Concept: Rational number can be represented in the form of  $\frac{p}{q}$ , where $q\neq 0$, and irrational number can not be represented in the form of  $\frac{p}{q}$

Given: $\frac{\sqrt{18} }{\sqrt{2} }$

To find: $\frac{\sqrt{18} }{\sqrt{2} }$ is a rational or irrational number

Solution:

     $\frac{\sqrt{18} }{\sqrt{2} }$

= $\frac{\sqrt{9*2} }{\sqrt{2} }$

= $\frac{3\sqrt{2} }{\sqrt{2} }$

= 3

Hence the simplest form   $\frac{\sqrt{18} }{\sqrt{2} }$ is 3, which is the rational number that can be written in the form of  $\frac{p}{q}$
