Answer:

As square root of 9 can be written in the required form for being a rational number, so it is a rational number

Explanation:

First of all we'll define rational numbers.

A number that can be written in the form p/q where p and q are integers and q≠0 is called a rational number.

Now we have to check if
√(9) is rational or not, we will check if it can be written in the form p/q


√(9) => (√(9))/(1) => (3)/(1)

As square root of 9 can be written in the required form for being a rational number, so it is a rational number
