    i don't really understand the "examples of rationalizing the denominator". What does it help you find?
    all the other videos are really helpful :)

    Rationalizing the denominator just means getting rid or the radical in the denominator. you're not allowed to have a radical in the denominator, so to remove it you do what is called "rationalizing the denominator" using the techniques in the videos...

    is "Rationalizing the denominator" a 506 topic or 566???

    It's a topic that was first introduced for the 566 class but is also important for the 506...
    Thanks for asking.
