8√9

Step-by-step explanation:

that is answer ok bye

Answer 2

Answer:

$\frac{1}{ \sqrt{5} + \sqrt{2} }$

On rationalizing,

$= \frac{1}{ (\sqrt{5} + \sqrt{2} ) } \times \frac{ (\sqrt{5} - \sqrt{2} )}{( \sqrt{5} - \sqrt{2}) }$

$= \frac{(\sqrt{5} - \sqrt{2})}{ ({ \sqrt{5} })^{2} - ( { \sqrt{2} })^{2} }$

$= \frac{ (\sqrt{5} - \sqrt{2})}{5 - 2}$

$= \frac{ (\sqrt{5} - \sqrt{2})}{3}$
