I can give the answer if you take a picture of the question.

I'm not sure if this is the question.

If this is the question then this will be the answer.

Answer 2

Answer:

$(\sqrt{9} -\sqrt{8} )/9$

Step-by-step explanation:

multiply numerator  and denominator with

$\sqrt{9} -\sqrt{8\\}$

as the denominator will be in the form (a+b)*(a-b)

it can be written as $a^{2} -b^{2}$

hence it will be $(\sqrt{9} -\sqrt{8} )/9$
