Question

Determine if The square root of 9 is rational or irrational and give a reason for your answer.

Answer 1

Answer:

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

Step-by-step 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 $\sqrt{9}$ is rational or not, we will check if it can be written in the form p/q

$\sqrt{9} => \frac{\sqrt{9}}{1} => \frac{3}{1}$

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