You can put this solution on YOUR website!
If the square number is even, then
\n" ); document.write( "it can be expressed as $\"+%28+2n%29%5E2+\"$
\n" ); document.write( "Because if it's square is even, the number
\n" ); document.write( "must be even.
\n" ); document.write( " $\"+%282n%29%5E2+=+4%2An%5E2+\"$
\n" ); document.write( "So, $\"+4%2An%5E2+\"$ is the square number and
\n" ); document.write( "is obviously divisible by $\"+4+\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
