Rationalising The Denominator | Algebra | Maths | FuseSchool
In this video we discover what rationalising the denominator is and how to do it. The denominator is the bottom part of a fraction. Rationalising the denominator is when we move a root from the bottom - the denominator - to the top (the numerator). For a surd to be in it’s simplest form, t

Why do we rationalize the denominator?
Our math teachers always tell us to "rationalize the denominator", but most of the time they don't tell us why. I'll leave it up to you to decide whether or not you think the reasons for rationalizing are good ones, but here are some of the reasons why we do it. 0:13 What we mean when we
