Answer 2

Heya mate!!

$\frac{30}{ \sqrt{20} + \sqrt{5} } \times \frac{ \sqrt{20} - \sqrt{5} }{ \sqrt{20} - \sqrt{5} } \\ \frac{30 \sqrt{20} - 30 \sqrt{5} }{20 - 5} \\ \frac{30 \sqrt{20} - 30 \sqrt{5} }{15} \\ \frac{30( \sqrt{20} - \sqrt{5} ) }{15} \\ 2 \sqrt{20} - 2 \sqrt{15}$

Hope it helps u dear✌️✌️
