Exponential and Logarithmic Functions

 Homework  page 442 (1-27) odd

 What exponent would you have to use to:  change 2 to 8?  change 7 to 1?  change 5 to 25?  change 3 to 81?  change 4 to 0.25?  When you are determining the exponent you would need to change a number to something else, you are finding the logarithm. Logarithms are exponents.

Evaluate each logarithm

Sometimes you will need to convert each number to a power of the same base.
