Explain Irrational numbers.
Irrational Numbers:
A number that cannot be expressed in the form $\frac{p}{q}$ where $p$ and $q$ are integers and $q$ is not equal to zero is an irrational number.
For example
$\sqrt{3}, \sqrt{7}, \pi$
Note: The value of Pi($\pi$) is not exactly equal to $\frac{22}{7}$.
We use it for calculation purposes. Therefore, $\pi$ is an irrational number.
