This lesson goes through a bunch of example problems of numbers to rational exponents. All steps are shown and explained for each problem. This is a great place to practice and make sure that you understand the concept. To learn how to do these problems or why this works, check out the earlier videos in the series. this video also begins introducing variables into this concept. Adding and subtracting fractional exponents is also covered as variables with fractional exponents are multiplied and divided at the end of this lesson.
