Introduction to Logarithms (1 of 2: Definition)

Eddie Woo6 minutes read

Logarithms represent exponential growth rates and relationships between final size, growth duration, and base numbers, such as 2 to the power of 5 indicating a doubling process. Equations like log base 3 of 81 illustrate the time needed for repeated tripling to reach a specific size, with the base denoting the growth rate.
