# Week 4: Rationalizing the Denominator

Hey, this week in Pre Calc 11 I learned something new that is difficult for me to understand. by me teaching this to you we both have a chance to learn more about rationalizing the denominator.

How to Rationalize the Denominator

ex. $\frac{1}{5\sqrt{3}}$

Step One: Multiply by the denominator

Step Two: Root the Radical Expression in the Denominator

Step Three: Simplify Further if Possible

FINAL ANSWER IS $\frac{\sqrt{3}}{15}$

Now you know how to remove a radical expression from the denominator. 🙂
