Answer 1

$Given : \frac{30}{5 \sqrt{3} - 3 \sqrt{5} }$

$\frac{30}{5 \sqrt{3} - 3 \sqrt{5} } * \frac{5 \sqrt{3} + 3 \sqrt{5} }{5 \sqrt{3} + 3 \sqrt{5} }$

$\frac{150 \sqrt{3} + 90 \sqrt{5} }{(5 \sqrt{3})^2 - (3 \sqrt{5})^2 }$

$\frac{150 \sqrt{3} + 90 \sqrt{5} }{75 - 45}$

$\frac{150 \sqrt{3} + 90 \sqrt{5} }{30}$

$\frac{30(3 \sqrt{5} + 5 \sqrt{3} ) }{30}$

$3 \sqrt{5} + 5 \sqrt{3}$


Hope this helps!
