👉 Learn how to evaluate basic logarithms. Recall that the logarithm of a number says a to the base of another number say b ...

\({\log _a}a = 1\) (since \({a^1} = a\)) so \({\log _7}7 = 1\) \({\log _a}1 = 0\) (since \({a^0} = 1\)) so \({\log _{20}}1 = 0\) \({\log _a}p + {\log _a}q = {\log _a ...

Description: 👉 Learn all about graphing logarithmic functions. A logarithmic function is a function with logarithms in them.
