1. Exponential Equations Objective: Solve Exponential equations

2. Exponential Equation: an equation containing a variable in an exponent Solving Exponential Equations by Expressing each side as a Power of the Same Base – 1. Rewrite the equation in the form – 2. Set – 3. Solve for the variable – Some exponential equations can’t be expressed as a power of the same base and that will be covered later in the Chapter. – All exponential functions are One-to-One functions

3. Ex: Solve each equation without using a calculator 1. 2. 3. 4.

4. EX: Applications OPTICS: If a single pane of glass obliterates 3% of the light passing through it, then the percent p of light that passes through n successive panes is given approximately by the function – A) What percent of light will pass through 10 panes? – B) What percent of light will pass through 25 panes?
