Logarithms and Logarithmic Functions Notes 8.4 (Day 1) Logarithms and Logarithmic Functions

Definition of a logarithm *** Read as “log base b of y equals x” *** IF a log does not have a base, it is assumed that it is base 10 *** All rules for logs apply for natural logs (ln), however if ln does not have a base, it is considered base e
