As my College Algebra class prepares for the Complex Number section that will lead to being able to solve just about any quadratic equation, here's a link to a worksheet on simplifying radicals. We will do a few of the first problems together in class. Answers are given, too!
Free Radical Practice from Kuta Software
Tip: It may help to review prime factorization. See the Pencast on this on the right side of this webpage for a tutorial. You can even make up your own numbers like 220, 175, 330 then check your factors at www.WolframAlpha.com. I went to WolframAlpha and entered "Factor(220)". Click here to see what it did for me! I also show how to have WolframAlpha simplify the square root of 220 here.
There's also a Radicals pencast to the right of this webpage.
