\n" ); document.write( "Use the rule:
\n" ); document.write( " $\"+log%28a%5Eb%29+=+b%2Alog%28a%29+\"$
\n" ); document.write( " $\"+log%285%29+=+x%2Alog%281.2%29+\"$
\n" ); document.write( "Divide both sides by $\"+log%281.2%29+\"$
\n" ); document.write( " $\"+x+=+log%285%29+%2F+log%281.2%29+\"$
\n" ); document.write( " $\"+x+=+.69897+%2F+.079181+\"$
\n" ); document.write( " $\"+x+=+8.8275\"$
