\r\n" );

document.write( "\r\n" );
document.write( "23 means 2×2×2 which is 8.  So now we have:\r\n" );
document.write( "\r\n" );
document.write( "  8×8-1\r\n" );
document.write( "\r\n" );
document.write( "and since 8 is the same as 81, we now have:\r\n" );
document.write( "\r\n" );
document.write( "  81×8-1\r\n" );
document.write( "\r\n" );
document.write( "Now add the exponents of 8 and get\r\n" );
