Lesson
In the previous lesson, the concept of zero and negative exponents was analyzed on a graph and its corresponding table. Read and study the Focus to find an algebraic method of verifying the result of investigation 3.
Both verifications are based on the law of exponents for dividing with the same base. Recall that law states:
If you have problems following the steps in these verifications consult with you teacher.
