Pell equation 썸네일형 리스트형 Problem 66 - Investigate the Diophantine equation x2 − Dy2 = 1. 링크 Consider quadratic Diophantine equations of the form: x2 – Dy2 = 1 For example, when D=13, the minimal solution in x is 6492 – 131802 = 1. It can be assumed that there are no solutions in positive integers when D is square. By finding minimal solutions in x for D = {2, 3, 5, 6, 7}, we obtain the following: 32 – 222 = 1 22 – 312 = 1 92 – 542 = 1 52 – 622 = 1 82 – 732 = 1 Hence, by considering .. 더보기 이전 1 다음
