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{\sqrt{3}}{\sqrt{32}} ,$ simplifies to \begin{array}{l}\require{cancel} \dfrac{\sqrt{3}}{\sqrt{32}}\cdot\dfrac{\sqrt{2}}{\sqrt{2}} \\\\= \dfrac{\sqrt{6}}{\sqrt{64}} \\\\= \dfrac{\sqrt{6}}{\sqrt{(8)^2}} \\\\= \dfrac{\sqrt{6}}{8} .\end{array}
