Yes and the proof is surprisingly simple. Let x = 1, y = 0. Work for noninteger D as well. OK, OK, don't hit me. ----- Original Message ----- From: <Jpr2718@aol.com> To: <math-fun@mailman.xmission.com> Sent: Friday, April 28, 2006 9:33 PM Subject: Re: [math-fun] Re: favorite theorem
But my favorite is that for D > 0, D an integer, not a square, x^2 - Dy^2 = 1 has a solution in integers.
