You can put this solution on YOUR website!
You only need 3 rules:
\n" ); document.write( "(1) $\"+log%28a%29+%2B+log%28b%29+=+log%28a%2Ab%29+\"$
\n" ); document.write( "(2) $\"+log%28a%29+-+log%28b%29+=+log%28a%2Fb%29+\"$
\n" ); document.write( "(3) $\"+b%2Alog%28a%29+=+log%28+a%5Eb%29+\"$
\n" ); document.write( "--------------------------
\n" ); document.write( " $\"+4%2Alog%28+x+%29+-+2%2Alog%28x%5E2%2B1%29+%2B+3%2Alog%28x-1%29+\"$
\n" ); document.write( "Rewrite the order of the terms:
\n" ); document.write( " $\"+4%2Alog%28+x+%29+%2B+3%2Alog%28x-1%29+-+2%2Alog%28x%5E2%2B1%29+\"$
\n" ); document.write( "Apply rule 3
\n" ); document.write( " $\"+log%28+x%5E4+%29+%2B+log%28+%28+x-1+%29%5E3+%29+-+log%28+%28+x%5E2+%2B+1+%29%5E2%29+\"$
\n" ); document.write( "Apply rules 1 and 2
\n" ); document.write( " $\"+log%28%28+x%5E4+%2A+%28+x-1%29%5E3+%29%29+-+log%28%28+%28+x%5E2+%2B+1+%29%5E2%29%29+\"$
\n" ); document.write( " $\"+log%28%28+x%5E4+%2A+%28+x-1%29%5E3+%29+%2F+%28+x%5E2+%2B+1+%29%5E2+%29%29+\"$
\n" ); document.write( " $\"+log%28%28+x%5E4+%2A+%28+x-1%29%5E3+%29+%2F+%28+x%5E2+%2B+1+%29%5E2+%29%29+\"$
\n" ); document.write( "I could expand everything, but that's not needed.\r
