WitrynaIn mathematics, logarithmic growth describes a phenomenon whose size or cost can be described as a logarithm function of some input. e.g. y = C log ( x ). Any logarithm base can be used, since one can be converted to another by multiplying by a fixed constant. [1] Logarithmic growth is the inverse of exponential growth and is very slow. Witryna27 sie 2024 · Definition. A logarithm is the answer to the question what power x do I need to apply to the base b in order to obtain the number y: log_b (y) = x is another way of specifying the relationship: b^x = y.
