If the radial expression is irrational to appear in the denominator, we rationalize the denominator

For example


\frac{5}{\sqrt[]{3}}

By rationalizing we are able to find the value by manual


\frac{5}{\sqrt[]{3}}=\frac{5*\sqrt[]{3}}{\sqrt[]{3}*\sqrt[]{3}}=\frac{5\sqrt[]{3}}{6}=1.443

Hence the answer is true.
