$\"log3%288x-7%29=4\"$
\n" ); document.write( "rewrite this as the exponent equiv of logs
\n" ); document.write( " $\"%288x+-+7%29+=+3%5E4\"$
\n" ); document.write( "which is
\n" ); document.write( "8x - 7 = 81
\n" ); document.write( "8x = 81 + 7
\n" ); document.write( "8x = 88
\n" ); document.write( "x = $\"88%2F8\"$
\n" ); document.write( "x = 11
