Hello

Something like this?

$\displaystyle \frac{\sqrt{63}}{3} + \frac{14}{\sqrt{7}}$

$\displaystyle =\frac{\sqrt{9}*\sqrt{7}}{3} + \frac{14\sqrt{7}}{7}$

$\displaystyle =\frac{3\sqrt{7}}{3} + 2\sqrt{7}$

$\displaystyle = \sqrt{7} + 2\sqrt{7}$

$\displaystyle = 3\sqrt{7}$

Does that help, can you follow the steps?
