\"3%5E%28x-1%29+=+2\" Take the loarithm of both sides.
\n" ); document.write( "\"%28x-1%29log%28%283%29%29+=+log%28%282%29%29\" Divide both sides by log(3).
\n" ); document.write( "\"x-1+=+%28log%28%282%29%29%29%2Flog%28%283%29%29\" Add 1 to both sides.
\n" ); document.write( "\"x+=+%28log%28%282%29%29%29%2Flog%28%283%29%29+%2B+1\" Evaluate using your calculator.
\n" ); document.write( "\"x+=+0.630929+%2B+1\"
\n" ); document.write( "\"x+=+1.6309\" to four decimal places.\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "\"3%5E%28x-1%29+=+2\" Substitute x = 1.6309
\n" ); document.write( "\"3%5E0.6309+=+1.9999346\" This is very close to 2.
\n" ); document.write( "
\n" );
