Now that you have learned the power law of logarithms, you can use the law to solve exponential equations. This means you can determine an exact value of t in equations like the E. coli growth equation you saw in Lesson 2. In this lesson you will learn how to solve exponential equations by applying the laws of logarithms.

 

Lesson Outcome

 

At the end of this lesson you will be able to solve exponential equations using logarithms.

 

Lesson Question

 

You will investigate the following question: How can logarithms be used to solve exponential equations?
