Answer 1

see ur ans here ....
I hope it help you ☺️

Answer 2

Given,

$\frac{6 \sqrt{5} - 5 \sqrt{3} }{2 \sqrt{3} + 4 \sqrt{5} }$

On rationalizing, We get

$\frac{(6 \sqrt{5} - 5\sqrt{3}) * (2 \sqrt{3} - 4 \sqrt{5})}{(2 \sqrt{3}+ 4 \sqrt{5}) *(2 \sqrt{3}- 4 \sqrt{5} )} }$

$\frac{32 \sqrt{15} - 150}{-68}$

$\frac{150 - 32 \sqrt{15} }{68}$

$\frac{2(75 - 16 \sqrt{15}) }{68}$

$\frac{75 - 16 \sqrt{15} }{34}$


Hope this helps!
