You can put this solution on YOUR website!
Easiest way for me is estimation.
\n" ); document.write( "Possibles (because of the first constraint) are 14,25,36,47,58,69
\n" ); document.write( "Let's start with one in the middle: 36
\n" ); document.write( "\"3%5E3\"=9; \"6%5E2\"=36; difference of 25 and 36 =11
\n" ); document.write( "\"2%5E2\"=4; \"5%5E5\"=25; difference of 21 and 25 = 4
\n" ); document.write( "\"1%5E2\"=1; \"4%5E2\"=16; difference of 15 and 14 = 1
\n" ); document.write( "Hmmm...
\n" ); document.write( "\"6%5E2\"=36;\"9%5E2\"=81; difference of 45 and 69 = 24
\n" ); document.write( "\"5%5E2\"=25; \"8%5E2\"=64; difference of 39 and 58 = 19
\n" ); document.write( "\"4%5E4\"=16; \"7%5E2\"=49; difference of 33 and 47 = 14
\n" ); document.write( "Unless I've miscalculated somewhere, there is no solution where the difference ends up to be 12.
\n" ); document.write( "
\n" ); document.write( "
\n" );
