摘要
首先利用递归数列的方法证明了不定方程x3+1=158y2仅有整数解(x,y)=(-1,0),(293,±399)。进而证明了不定方程x3+8=79y2仅有整数解(x,y)=(-2,0),(586,±1596)。
By using the method of recurrent sequence, the author proves that the Diophantine equation x3 + 1 = 158y2 has only the integer solution (x, y) = (-1,0), (293, ± 399), then proves that the Diophantine x3+8 = 79y2has only the integer solution ( x, y) = ( -2,0 ), ( 586,± 1596 ).
