You can put this solution on YOUR website!
8x = 2^(x-2) solve x
\n" ); document.write( "rewrite the 8 as a power of 2
\n" ); document.write( " $\"2%5E3%2Ax+=+2%5E%28%28x-2%29%29\"$
\n" ); document.write( "x = $\"%282%5E%28x-2%29%29%2F%282%5E3%29\"$
\n" ); document.write( "x = $\"2%5E%28x-2-3%29\"$
\n" ); document.write( "x = $\"2%5E%28x-5%29\"$
\n" ); document.write( "we know that x is a power of 2 greater than 5, x=8 is the obvious answer, \n" ); document.write( "

\n" );
