Remember $\"+log%28a%29%2Blog%28b%29=log%28ab%29+\"$
\n" ); document.write( "and $\"+log%28a%29-log%28b%29=log%28a%2Fb%29+\"$
\n" ); document.write( "and $\"+nlog%28a%29log%28a%5En%29+\"$ \r
\n" ); document.write( "\n" ); document.write( "

\n" ); document.write( "

\n" ); document.write( " $\"+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=log+%28%287%29%287%29%29+\"$
\n" ); document.write( " $\"+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=log+%287%5E2%29+\"$
\n" ); document.write( " $\"+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=2log+%287%29+\"$
\n" ); document.write( " $\"+log+21+%2B+log+77+%2B+log+88+-+log+121+-log+24+=2+\"$ as using base 7 logs so $\"+log+%287%29=1+\"$ \r
