Answer 2

Solution

$1) \: \frac{ \sqrt{10} }{5 \sqrt{2} + 3 \sqrt{5} } \\ \\ \implies \frac{ \sqrt{10 } \times (5 \sqrt{2} - 3 \sqrt{5}) }{(5 \sqrt{2} + 3 \sqrt{5} )(5 \sqrt{2} - 3 \sqrt{5}) } \\ \\ \implies \frac{5 \sqrt{20 } - 5 \sqrt{50} }{ {(5 \sqrt{2)} }^{2} - {(3 \sqrt{5)} }^{2} } \\ \\ \implies \frac{5( \sqrt{20} - \sqrt{50}) }{10 - 15} \\ \\ \implies \frac{5( \sqrt{20} - \sqrt{50} )}{ - 5} \\ \\ \implies - (\sqrt{20} - \sqrt{50} ) \\ \\ \implies \sqrt{50} - \sqrt{20} \\ \\ \implies \sqrt{2 \times 5 \times 5} - \sqrt{2 \times 2 \times 5} \\ \\ \implies5 \sqrt{2} - 2 \sqrt{5}$
