\({\log _a}a = 1\) (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 ...

Watch this video to learn about straight line graphs of logarithmic and exponential functions ... This implies the formula of this growth is \(y = k{x^n}\), where \(k\) and \(n\) are constants.
