Answer 1

$\red{\boxed{\boxed{AnswEr:-}}}$

$\frac{1}{ \sqrt{5} + \sqrt{2} } \\ rationalization \\ \frac{1}{ \sqrt{5} + \sqrt{2} } \times [ \frac{ \sqrt{5} - \sqrt{2} }{ \sqrt{5} - \sqrt{2} } \\ \frac{ \sqrt{5} - \sqrt{2} }{5 - 2} = \frac{ \sqrt{5} - \sqrt{2} }{3}$

Hope it helps☺!

Answer 2

Answer:

=> 1/√2+√5 × √2-√5/√2-√5
