Powers of fractions (Full video)

Khan Academy

Supporting grades: 6

Description: Just like whole numbers with exponents, fractions are repeatedly multiplied. If you know how to multiply fractions, you're over half way there. Created by Sal Khan. So let's say I have 2/3, and I want to raise it to the third power here. Now, the other way of viewing this is you start with a 1, and you multiply it by 2/3 three times. When I raise something to the second power, people often say, you're squaring it.
