Answer 1

$\huge {\textbf {\underline {\underline {ANSWER}}}}$

$\frac{ \sqrt{2} + 1 }{ \sqrt{5} } \\ \\ \\ = \frac{( \sqrt{2} + 1)( \sqrt{5)} }{ \sqrt{5} \times \sqrt{5} } \\ \\ \\ = \frac{ \sqrt{10} + \sqrt{5} }{5} \\ \\ \\ = \frac{3.162 + 2.236}{5} \\ \\ \\ = \frac{5.893}{5} \\ \\ \\ = 1.138$

Thanks
