Hello!
In order to rationalize the denominator, we need to make use of the following rule:

The denominator in your case is so in order to eliminate the square root ("rationalize it"), we can multiply it by . Of course, we must multiply the numerator too by that number. So we have:

So your expression becomes:

So now we've rationalized the denominator.

I hope this helps!
