# How do you simplify sqrt(6/3) -sqrt(9/3)?

$\sqrt{\frac{6}{3}} - \sqrt{\frac{9}{3}} = \textcolor{red}{\sqrt{2} - \sqrt{3}}$
$\frac{6}{3} = 2 \textcolor{w h i t e}{\left\langle\text{xxxx}\right)}$ and $\textcolor{w h i t e}{\text{xxxx}} \frac{9}{3} = 3$
No exact simplification of $\sqrt{2} - \sqrt{3}$ is possible
