You can put this solution on YOUR website!
Use the fact that:
\n" ); document.write( " $\"a%5En%2Aa%5Em+=+a%5E%28m%2Bn%29\"$
\n" ); document.write( " $\"3%5E%282.5%29+=+3%5E%28%282%2B0.5%29%29\"$ = $\"3%5E2%2A3%5E0.5\"$ = $\"9%2Asqrt%283%29\"$
\n" ); document.write( " $\"5%5E%281.3%29+=+5%5E%28%281%2B0.3%29%29\"$ = $\"5%5E1%2A5%5E%280.3%29+=+5%2A5%5E%280.3%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"5%5E%280.3%29+=+1.62065659669\"$ ... I don't know how you would get this manually!
\n" ); document.write( " $\"5%5E%281.3%29+=+5%2A1.62\"$ = $\"8.1\"$ approx.
\n" ); document.write( " \n" ); document.write( "

\n" );
