8.5 Exponential and Logarithmic Equations The best and safest thing is to keep a balance in your life, acknowledge the great powers around us and in us.

We will use logarithms to undo exponents. We will use this property of logarithms:

Exponential Equations Take the common logarithm of both sides

Exponential Equations By graphing… 1. Graph: 2. Find point of intersection (2nd -> Calc -> Intersect) calc

Logarithmic Equations Change of Base Formula: Ex: Evaluate

Logarithmic Equations When x is in the argument of the logarithm and nothing can be moved around…convert equation to an exponential function.

Logarithmic Equations When there are multiple logarithms… Write as a single logarithm, THEN put in exponential form!

8.5 Exponential and Logarithmic Equations HW: 1-13 odd, 25-47 odd The best and safest thing is to keep a balance in your life, acknowledge the great powers around us and in us.
