Logarithms: definition, properties and worked examples
The logarithm of a in base b is the exponent x such that b^x = a, with b > 0, b ≠ 1 and a > 0. The key rules are log(xy) = log x + log y, log(x/y) = log x − log y, log(xⁿ) = n · log x and the change of base log_b a = log a / log b. Logarithms turn exponential equations into linear ones.
