Lesson 5 Summary

 

In this lesson you learned the following three laws of logarithms:

  • logb M + logb N = logb(M × N)
  • logb (MN) = n logb M

These laws can be used to manipulate expressions to a more desirable form. In the next lesson you will see how these can be used to help solve exponential equations.
