  3. Apply the Product, Quotient, and Power Properties of Logarithms Let b, x, and y be positive real numbers where b ≠ 1. Product Property: Quotient Property: Power Property: For these exercises, assume that all variable expressions represent positive real numbers.

  4. Examples 1 – 3: Use the product property of logarithms to write the logarithm as a sum. Then simplify if possible. 1. 2. 3.

  5. Examples 4 – 6: Use the quotient property of logarithms to write the logarithm as a difference. Then simplify if possible. 4. 5. 6.
