c)
\frac{2-\sqrt6}{\sqrt3}=\frac{(2-\sqrt6)*\sqrt3}{\sqrt3*\sqrt3}=\frac{2\sqrt3-\sqrt{18}}{3}=\frac{2\sqrt3-3\sqrt2}{3}
f)
\frac{9\sqrt6-6\sqrt{10}}{3\sqrt2}=\frac{3\sqrt2(3\sqrt3-2\sqrt5)}{3\sqrt2}=3\sqrt3-2\sqrt5
l)
\frac{\sqrt[3]3-\sqrt[3]{6}}{\sqrt[3]3}=\frac{\sqrt[3]3(1-\sqrt[3]{2})}{\sqrt[3]3}=1-\sqrt[3]2
i)
\frac{3}{\sqrt[3]3}=\frac{3*\sqrt[3]{9}}{\sqrt[3]{3}*\sqrt[3]9}=\frac{3\sqrt[3]9}{\sqrt[3]{27}}=\frac{3\sqrt[3]9}{3}=\sqrt[3]9
