To evaluate a logarithmic expression, convert to its corresponding exponential form and solve.

Example Evaluate

EvalLogs1-1

Step 1. Convert the log to its equivalent exponential form.

EvalLogs1-2

Step 2. Solve for x by rewriting 16 as a power with a base of 2.

EvalLogs1-3

Step 3. Substitute 24 in for 16 in step 1.

EvalLogs1-4

Step 4. Now that the bases are equal, set the exponents equal to each other.
