The original problem is:
\n" ); document.write( " $\"log3%28a-2%29%2Blog3%28a-2%29=2\"$
\n" ); document.write( "using the addition rule, we get
\n" ); document.write( " $\"log_3%28a-2%29%5E2+=+2\"$
\n" ); document.write( "rewriting as exponents, we get
\n" ); document.write( " $\"3%5E2+=+%28a-2%29%5E2\"$
\n" ); document.write( "and solving for x, we get
\n" ); document.write( "a = 5. \n" ); document.write( "

\n" );
