Is this the problem?
\n" ); document.write( " $\"ln%28x%29%2Bln%283x%29=12\"$
\n" ); document.write( "From the log rules,
\n" ); document.write( " $\"ln%28a%29%2Bln%28b%29=ln%28ab%29\"$
\n" ); document.write( "Then
\n" ); document.write( " $\"ln%28x%29%2Bln%283x%29=12\"$
\n" ); document.write( " $\"ln%283x%5E2%29=12\"$
\n" ); document.write( " $\"3x%5E2=e%5E12\"$
\n" ); document.write( " $\"x%5E2=e%5E12%2F3\"$
\n" ); document.write( " $\"x=sqrt%28e%5E12%2F3%29\"$ and $\"x=-sqrt%28e%5E12%2F3%29\"$
\n" ); document.write( "x=232.92 and x=-232.92
\n" ); document.write( "Check your answers.
\n" ); document.write( " $\"ln%28x%29%2Bln%283x%29=12\"$
\n" ); document.write( " $\"ln%28232.92%29%2Bln%28698.76%29=12\"$
\n" ); document.write( " $\"5.45%2B6.55=12\"$
\n" ); document.write( " $\"12=12\"$
\n" ); document.write( "True statement.
