Question

pls answer by step by step

Answer 1

Answer:

$\frac{\sqrt{5}-\sqrt{2} }{3}$

Step-by-step explanation:

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

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

$\frac{\sqrt{5} - \sqrt{2} }{(\sqrt5)^{2} - \sqrt{2})^2 } }$

$\frac{\sqrt{5} - \sqrt{2} }{5-2}$

$\frac{\sqrt{5}-\sqrt{2} }{3}$
