Show answer & explanation

Correct answer: D

Solution: apply logarithm properties to combine terms.

  • Step 1: Use subtraction rule for logarithms: log(9/8) - log(27/32) = log((9/8) ÷ (27/32)).

  • Step 2: Simplify the fraction: (9/8) ÷ (27/32) = (9/8) · (32/27) = 288/216 = 4/3, so the difference equals log(4/3).

  • Step 3: Add the remaining term: log(4/3) + log(3/4) = log((4/3)·(3/4)) = log(1) = 0.
