Big Idea The main idea of this lesson is that students compare dividing radicals by hand without rationalizing and realize why rationalizing came about and how it works. Rationalizing is the process of starting with a fraction containing a radical in its denominator and determining fraction with no radical in its denominator. In simplifying radical expressions, you only need to use absolute value to ensure that the expression cannot yield an invalid result if the radical index n is even (i.e., {2, 4, 6, …}) and: √ can be rewritten as: ( ) ( ) such that evenpower is less than the radical index n so that taking the root of ( ) will fully simplify the radical. It can also be used the other way around to split a radical into two if there's a fraction inside. Did you know… We have over 220 college 23 27x6 5.
