Solving exponential and logarithmic equations — Homework
Decide first whether the bases can match; if not, take logs of both sides.
- 1.Solve: 3^(x+2) = 27.
- 2.Solve: log_5(x+1) = 2.
- 3.Solve: 4^(3x) = 64.
- 4.Solve 6^x = 40 for x, giving an exact log expression and a decimal approximation (3 decimal places).
- 5.Solve log_2(x) + log_2(x-2) = 3, and identify any extraneous solution.
