Answer
$\color{blue}{\dfrac{\sqrt{7}}{6}}$
Work Step by Step
RECALL:
For $a\gt0$ and $b\gt0$,
$\sqrt{\dfrac{a}{b}}=\dfrac{\sqrt{a}}{\sqrt{b}}$
Use the rule above to obtain:
$=\dfrac{\sqrt{7}}{\sqrt{36}}
\\=\dfrac{\sqrt{7}}{\sqrt{6^2}}$
Since $\sqrt{6^2}=6$, then the expression above simplifies to
$=\color{blue}{\dfrac{\sqrt{7}}{6}}$
