You you use the conjugate of  sqrt17 - sqrt 2  which is sqrt17 + sqrt2

so the fraction is   sqrt17 + sqrt2

Given radical expression: \frac{3}{\sqrt{17}-\sqrt{2}}.

We need to find the fraction by which fraction will produce an equivalent fraction with a rational denominator.

In the given expression, we have \sqrt{17}-\sqrt{2}.

Which is an irrational number in denominator.

In order to get rid irrational number from denominator and get a rational number in denominator, we need to multiply given expression by conjugate of the denominator.

The conjugate of \sqrt{17}-\sqrt{2} is \sqrt{17}+\sqrt{2}.

<h3>Therefore, we need to multiply \frac{3}{\sqrt{17}-\sqrt{2}} by \frac{\sqrt{17}+\sqrt{2}}{\sqrt{17}+\sqrt{2}} fraction that will produce an equivalent fraction with a rational denominator.</h3>
