GED Math Chapter 8: Powers and Exponents Lesson 6

Wow!  you really have been working hard at growing your math skills- I’m proud of you!  Let’s finish this chapter up by looking at exponential growth and decay.  This is a big topic but my lesson will only be an introduction to some important concepts.  Nevertheless, you will see how powers and exponents are used in other areas of mathematics.

Things to focus on in this lesson:

• what is exponential growth
• what is decay
• the basic exponential growth and decay formulas

  • being able to work with fractions and positive and negative numbers
  • being able to solve equations and inequalities
  • knowing how to graph lines
  • knowing how to work with powers and exponents

In the next chapter we will study rational expressions- let’s get started!

Hello John, I am writing to thank you. During the Summer I took and passed all of my GED courses with the exception of the Math test. I found your free math course online and listened and watched all of the videos, trying to educate myself utilizing the tools and tips that you provided. I have to admit, it was very overwhelming and at times I felt as though I was being taught in a foreign language. I scheduled my re-test earlier this week and I passed. Thank you from the bottom of my heart. It took me 22 years to feel confident enough to achieve this goal and I am forever grateful to you for offering this information online. You are heaven sent! Now I can apply for better paying jobs and attend college. Thank you, thank you, thank you for helping others change their lives for the better!!” Sincerely, Alicia
