Because you can multiply logarithms, you can also take powers <strong>of</strong> logarithms.
Example 5: Simplifying <strong>Logarithms</strong> with Exponents Express as a product. Simplify, if possible. A. log 2 32 6 B. log 8 4 20 6log 2 32 6(5) = 30 Because 2 5 = 32, log 2 32 = 5. 20log 8 4 20( ) = 40 2 3 3 Because 2 3 8 = 4, 2 log 4 = . 8 3
