Understanding Logarithm Condensation

What is Logarithm Condensation?

Logarithm condensation is the process of combining multiple logarithmic expressions into a single logarithm using the fundamental properties of logarithms. This technique is the reverse of logarithm expansion and is useful for simplifying complex logarithmic expressions.

Key Rules

  • Addition: log(a) + log(b) = log(a·b)
  • Subtraction: log(a) - log(b) = log(a/b)
  • Coefficient: x·log(a) = log(a^x)

Why Condense Logarithms?

  • Simplifies complex expressions
  • Makes calculations easier
  • Useful in solving logarithmic equations
  • Essential in calculus and advanced mathematics

Note: All logarithms must have the same base for condensation rules to apply directly.

Example: Condensing 3·log₆(4) + log₆(9)

13·log₆(4) + log₆(9)Original expression
2log₆(4³) + log₆(9)Apply power rule
3log₆(64) + log₆(9)Calculate 4³ = 64
4log₆(64 × 9)Apply product rule
log₆(576)Final condensed form
