Answer 1

$\frac{2}{ \sqrt{5} } = \frac{2 \sqrt{5} }{5} = \frac{2 \times 2.236}{5} = \frac{4.472}{5} = 0.894$
$\frac{2 - \sqrt{3} }{ \sqrt{3} } = \frac{2 \sqrt{3} - 3}{3} = \frac{2 \times 1.732 - 3}{3} \\ = \frac{3.464 - 3}{3} = \frac{0.464}{3} = 0.154$
$\frac{ \sqrt{10} - \sqrt{5} }{ \sqrt{2} } = \frac{ \sqrt{5} \times \sqrt{2} - \sqrt{5} }{ \sqrt{2} } = \frac{2 \sqrt{5} - \sqrt{10} }{2}$
Please solve the last one yourself it's difficult to type it in the phone!!!
Hope this helps...

Answer 2

Hey friend,
Here is the answer you were looking for:
$1) \frac{2}{ \sqrt{5} } \\ \\ = \frac{2}{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } \\ \\ = \frac{2 \times \sqrt{5} }{ \sqrt{5} \times \sqrt{5} } \\ \\ = \frac{2 \sqrt{5} }{5} \\ \\ = \frac{2 \times 2.236}{5} \\ \\ = \frac{4.472}{5} \\ \\ 2) \frac{2 - \sqrt{3} }{ \sqrt{3} } \\ \\ = \frac{2 - \sqrt{3} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } \\ \\ = \frac{2 \times \sqrt{3} - \sqrt{3} \times \sqrt{3} }{ \sqrt{3} \times \sqrt{3} } \\ \\ = \frac{2 \sqrt{3} - 3}{3} \\ \\ = \frac{2 \times 1.732 - 3}{3} \\ \\ = \frac{3.464 - 3}{3} \\ \\ = \frac{0.464}{3} \\ \\ 3) \frac{ \sqrt{10} - \sqrt{5} }{ \sqrt{2} } \\ \\ = \frac{ \sqrt{10} - \sqrt{5} }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ \\ = \frac{ \sqrt{10} \times \sqrt{2} - \sqrt{5} \times \sqrt{2} }{ \sqrt{2} \times \sqrt{2} } \\ \\ = \frac{ \sqrt{10 } \times \sqrt{2} - \sqrt{10} }{2} \\ \\ = \frac{3.162 \times 1.414 - 3.162}{2} \\ \\ = \frac{4.471 - 3.162}{2} \\ \\ = \frac{1.309}{2}$


Hope this helps!!!
