Answer 2

√(13/117) is a rational number as √(13/117) can be written in the form p/q where p & q are integers with q ≠ 0

Correct question : √(13/117) is it rational, how?

Given :

$\displaystyle \sf \: number \: \: \sqrt{ \frac{13}{117} }$

To find :

The reason for the number is rational

Solution :

Step 1 of 2 :

Write down the given number

Here the given number is

$\displaystyle \sf \sqrt{ \frac{13}{117} }$

Step 2 of 2 :

Find the reason for the number is rational

$\displaystyle \sf \sqrt{ \frac{13}{117} }$

$\displaystyle \sf = \sqrt{ \frac{1}{9} }$

$\displaystyle \sf = \frac{1}{3}$

Which can be written in the form p/q where p = 1 & q = 3

Since √(13/117) can be written in the form p/q where p & q are integers with q ≠ 0
