| Abstract: | The following conclusion is proved:If D is an even square-free integer,D=2 Πk i=1 pi Πl j=1 qj,pi≡3,11,13,17,19,23,29,31,37(mod40),qj≡3,7,11,19,23,31(mod40),或qj≡1,5,13,17,19,29,37(mod40),l≤3,where pi,qj are different odd prime,then the equations in title only have a non-trivial solution D=2,(x,y,z)=(19,6,4). |
