Do you want to simplify it? Then just write: $\displaystyle \frac{18}{\sqrt{3}}=\frac{6\cdot 3}{\sqrt{3}}=6\sqrt{3}$
Alternatively, $\displaystyle \frac{18}{\sqrt{3}}\cdot\frac{\sqrt{3}}{\sqrt{3}}= \frac{18\sqrt{3}}{3}=6\sqrt{3}$

thanks guys but could you also post how you got this so i can understand it please?

what would i do if i had to write it inform of k square root 3??
$\displaystyle 6\sqrt{3}$ is in the form $\displaystyle k\sqrt{3}$ as $\displaystyle k$ refers to an unknown integer which you are expected to determine.
so k=6?
Exactly.
