Answer

ymeansby=xy means b^y = x

A logarithm answers the question: "What exponent do I need?"

log_b(x) = y means b^y = x

Example: log₂(8) = 3 because 2³ = 8

Key properties: • log(ab) = log(a) + log(b) • log(a/b) = log(a) − log(b) • log(aⁿ) = n·log(a) • log_b(1) = 0 (anything to the 0 is 1) • log_b(b) = 1

Common bases: log₁₀ (common log, written as "log"), logₑ (natural log, written as "ln"), log₂ (used in computer science).
