The 0 & 1st power (Full video)

Khan Academy

Supporting grades: 8

Description: Discover a pattern that explains why any non-zero number to the zero power equals one. Created by Sal Khan. What I want to do in this video is think about exponents in a slightly different way that will be useful for different contexts and also go through a lot more examples. So in the last video, we saw that taking something to an exponent means multiplying that number that many times. So if I had the number negative 2 and I want to raise it to the third power, this literally means taking three negative 2's, so negative 2, negative 2, and negative 2, and then multiplying them.
