Question

True or false: when radical expressions appear in the denominator of a quotient, we rationalize the denominator?

Answer 1

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.
