This Olympiad-style exponential problem looks simple at first — until you try solving it. Test your skills and see if you can crack it before I walk through the clever solution step-by-step.

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