摘要
本文证明了丢番图方程x4-4x2y2+y4=526仅有正整数解(x,y)=(1,5)和(5,1),从此又推得方程x4-10x2y2+y4=-263仅有正整数解(x,y)=(2,3)和(3,2)。
In this paper, we prove the following theorems: theorem the Diophantine equation x4-4x2y2+y4= 526 has only positive integer solution (x, y)=(1, 5) and(5, 1).Corollary the Diophantine equation x4- 10x2y2+ y4= - 263 has only positive integer solution (x, y)=(2, 3) and (3, 2).
