Today we understood why any number raised to the zero power equals 1. We looked at division and multiplication that we had previously learned to explain this concept.
This lesson involved raising products and quotients to powers themselves. It builds on the exponent rules that students have already learned.
Today we looked at performing operations on expressions written in exponential notation--specifically we multiplied and divided exponents that have the same base. Students are set up well to understand what happens when we raise powers to powers, which is the next lesson.
