The things that I found easy about this unit is, putting mixed radicals into entire radicals, and vice versa. The thing that I found more difficult that I now understand is rationalizing denominators. It didn't make much sense off the start but once I found out that you are just multiplying both sides by the conjgute, and then you are just simplifying it seemed alot easier. I haven't seen when you would use the things from this unit outside of school but I could see how you could use this outside of school.
