📚 Quick Study Guide

  • 🔑 Definition: Logarithms are the inverse operation to exponentiation. The logarithm of a number $x$ with respect to base $b$ is the exponent to which $b$ must be raised to produce $x$. This is written as $\log_b(x) = y$, which means $b^y = x$.
  • Product Rule: $\log_b(MN) = \log_b(M) + \log_b(N)$
  • Quotient Rule: $\log_b(\frac{M}{N}) = \log_b(M) - \log_b(N)$
  • 💪 Power Rule: $\log_b(M^k) = k \cdot \log_b(M)$
  • 🔄 Change of Base Formula: $\log_b(a) = \frac{\log_c(a)}{\log_c(b)}$
  • 📈 Common Logarithm: A logarithm with base 10, denoted as $\log(x)$ or $\log_{10}(x)$.
  • 🌿 Natural Logarithm: A logarithm with base $e$ (Euler's number, approximately 2.718), denoted as $\ln(x)$ or $\log_e(x)$.
