## How to Find if the Value is Rational or Irrational?

A **rational number** is a number that is of the form p/q where p and q are integers and q is not equal to 0. For example 6/2, 15/3,...

**Irrational numbers** are those real numbers that cannot be represented in the form of a ratio p /q. In other words, those real numbers that are not rational numbers are known as irrational numbers. For example π, e, √13,...

Check whether the expression **a ^{1/x}** is rational or irrational.

Let's see an example to understand briefly.
