Remember +log%28a%29%2Blog%28b%29=log%28ab%29+
and +log%28a%29-log%28b%29=log%28a%2Fb%29+
and +nlog%28a%29log%28a%5En%29+


+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=log+%28%287%29%287%29%29+
+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=log+%287%5E2%29+
+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=2log+%287%29+
+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=2+ as using base 7 logs so +log+%287%29=1+
