This states simplify, add, subtract, multiply, and divide expressions containing square roots.
Now this is simple first you need to know how to break down a radical. All you have to do is use the factor tree and give two multiples and break those down until they can't be simplified any more then you circle your pairs. If their is one pair you bring one number from the pair out and then multiply it by the number that was originally out side the radical If their is no number their then we know it represents an invisible one. After that you put the paired number outside the radical then the one that did not pair up it goes inside the radical. If theirs more than one number that did not pair up then you multiple those together and put the product inside the radical. Now if their more than one pair then one number from each pair drops out those are multiplied and by the number that was originally outside the radical. Here's a video explain more: http://www.youtube.com/watch?v=ucnKcrg5TrQ&feature=player_detailpage.
Here is a video explaining radical expressions: http://www.youtube.com/watch?v=fHAO7xkXz6k&feature=player_detailpage. After you have watched the video you have just seen another way to break it down it does not matter whether you do it that way or the way you just saw in the previous video.

This topic can be confusing but put it in the order that you will understand to perform it correctly and get the correct answer.
