Answer 1

Explanation:

If a number is rational, we can represent it as a fraction.

`(a)/(b)`

Where a and b are intergers.

First, we know that

`√(49) = 7`

We can represent 7 as

`(7)/(1) ..... (14)/(2) .... (21)/(3) ..... (n)/(y) = 7`

Where n and y are two numbers that when divided equal 7.

So

`√(49)`

is a rational number
