You would use logarithms to solve this kind of problem.
\n" ); document.write( " $\"12%5Ex+=+527\"$ Take the log of both sides.
\n" ); document.write( " $\"log%28%2812%5Ex%29%29+=+log%28%28527%29%29\"$ Apply the power rule to the left side.
\n" ); document.write( " $\"x%2Alog%28%2812%29%29+=+log%28%28527%29%29\"$ Now divide both sides by $\"log%28%2812%29%29\"$
\n" ); document.write( " $\"x+=+%28log%28%28527%29%29%29%2F%28log%28%2812%29%29%29\"$ Evaluate using your calculator.
\n" ); document.write( " $\"x+=+2.522\"$ \n" ); document.write( "

\n" );
