Unit Summary 2

For the second unit in precalculus 11, we learned how to multiply and divide radicals. In order to solve these equations we had too factor and we could verify our solutions. I will be demonstrating how to make an entire radical into a mixed radical, this was used in order to make the equation a lot easier. In order to make an entire radical into a mixed you need to find the factors (if it is square rooted you need to find the perfect square factors, and if it is cube rooted, you need to find the perfect cube factors.) here is an example:

Now that I have explained how to convert a entire radical into a mixed radical I will show explain how to convert a mixed radical into an entire radical. So when you have a mixed radical and you want to have the entire radical you first need to square the coefficient and then once you have done that then all you need to do is multiply the two square roots as you would with regular numbers and you will have your entire radical. example:
