Answer
$\sqrt{3}$
Work Step by Step
Recall, we are not allowed to have radicals in the denominator of a fraction. Using the properties of radicals, the given expression, $
\dfrac{3\sqrt{2}}{\sqrt{6}}
,$ simplifies to
\begin{array}{l}\require{cancel}
3\sqrt{\dfrac{2}{6}}
\\\\=
3\sqrt{\dfrac{1}{3}}
\\\\=
3\sqrt{\dfrac{1}{3}\cdot\dfrac{3}{3}}
\\\\=
3\sqrt{\dfrac{3}{9}}
\\\\=
\dfrac{3\sqrt{3}}{\sqrt{9}}
\\\\=
\dfrac{3\sqrt{3}}{\sqrt{(3)^2}}
\\\\=
\dfrac{3\sqrt{3}}{3}
\\\\=
\dfrac{\cancel{3}\sqrt{3}}{\cancel{3}}
\\\\=
\sqrt{3}
.\end{array}
