Answer 4

\[1/ ( 11 x \sqrt{5} ) - 4 y \sqrt{3}\]

Answer 5

is it 1/ the whole thing?

Answer 6

Is it like this :
\[\frac1{11x\sqrt5-4y\sqrt3}\]
or :

Answer 7

the second thing

Answer 8

OK !
We have :
\[\frac1{11x\sqrt5}-4y\sqrt3=\frac{1-44xy\sqrt{15}}{11x\sqrt5}=\frac{\sqrt5-220xy\sqrt3}{55x}\]
