Answer
$\frac{6\sqrt 7}{7}$
Work Step by Step
The simplification of the expression is only possible through rationalizing the denominator:
Step 1: $\frac{\sqrt {36}}{\sqrt 7}$
Step 2: $\frac{\sqrt {6^{2}}}{\sqrt 7}\times\frac{\sqrt 7}{\sqrt 7}$
Step 3: $\frac{6}{\sqrt 7}\times\frac{\sqrt 7}{\sqrt 7}$
Step 4: $\frac{6\sqrt 7}{(\sqrt 7)^{2}}$
Step 5: $\frac{6\sqrt 7}{7}$
