Solving exponential and logarithmic equations.

1. 3.4: Exponential and
Logarithmic Equations
Objective: Solve exponential and
logarithmic equations.

2. Strategies for solving logarithmic and
exponential equations:
1) Rewrite in inverse form and use one-to-
one properties
2) For exponential equations, isolate the
base and log both sides.
3) For logarithmic functions, isolate the
log and exponentiate both sides.

9. Applications!
Ex. 7) You have deposited $1000 in an
account that pays 6.25% interest,
compounded continuously. How long will it
take your money to double?
