I need to find a counterexample to the statement $\"4%5En%2B1\"$
\n" ); document.write( "is divisible by $\"5\"$ . Can someone please show me how to do this.
\n" ); document.write( "

\r\n" );
document.write( "Start with .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "No. that's not it, because  is divisible by .\r\n" );
document.write( "\r\n" );
document.write( "So try \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "There your counterexample.  is not divisible by .\r\n" );
document.write( "\r\n" );
document.write( "Edwin
