2 By the end of this lesson, I will be able to answer the following questions… 1. How can I solve a basic exponential equation? 2. How can you determine the whether the sum or product of two numbers will be rational or irrational AND determine closure? 3. Can I apply properties of exponent to solve solve growth and decay scenarios?
