1. 7.4 Exponential & Logarithmic Equations

2. 7.4 Notes Strategy for solving exponential equations:
Take the appropriate log of each side.
Example: e2x = You would take the natural log of each side.
Strategy for solving logarithmic equations:
- Rewrite as a exponential equation.
Example: log24x = 3 would become 23 = 4x and we would solve this equation.
