• 1. Solving Exponential Equations
• 2. Real World Use of Exponential Functions &#x2022; &#x2022; &#x2022; &#x2022; &#x2022; Population Growth Money (Compound Interest) Depreciation (Cars) Half-Life (Radioactive Material) Bacteria Growth
• 3. Exponential Equations &#x2022; One way to solve exponential equations is to use the property that if 2 powers w/ the same base are equal, then their exponents are equal. &#x2022; For b&gt;0 &amp; b&#x2260;1 if x b = y, b then x=y
• 4. Solve by equating exponents 3x 3 9 2 2 3x 3 9 x 4 Since they have the same bases we can set their exponents equal to each other and solve for x. 34 3 Check &#x2192; 2 29 29 9 2
