Strategies for condensing logarithms
  • If there is a number in front of the log, move it
    back to an exponent FIRST.
  • Write fraction exponents as radicals.
  • If there is a number raised to a power, simplify.
  • Condense addition back to multiplication and
    subtraction back to division.
  • The final answer will have log written only ONCE
    and will have no fractions as exponents.
