摘要
讨论不定方程x3+27=91y2的整数解.方法主要利用同余,递归数列,以及Pell方程的性质,给出了不定方程x3+27=91y2仅有整数解(-3,0),(4,±1);推广了不定方程的研究范围,为进一步研究提供了方向.
This paper discusses that the Diophantine equation x3+27=91y2only has integer solutions ( - 3,0) and(4, ± 1 ) with the help of the congruence expression,the nature of recurrent sequences and the property of Pell equation. The research range of the Diophantine equation is extended, which reveals the direction for further research.
