摘 要: | b对于适合a〈b的正整数a和b,如果∑1=a^bi=ab,则称(a,b)是一对友好数。运用PeⅡ方程x^2-2y^2=±1的解序列的递归性,得到了方程∑1=a^bi=ab的全部正整数解,从而给出了所有的友好数对。

Abstract: | For positive integers a and b with a 〈 b, ∑1=a^bi=ab, then (a,b) is called a friendly number pair. b i=a All positive integer solutions to the equation ∑1=a^bi=ab is proposed in this issue by using the reeursive property of i=a solution sequence of the Pell equations x^2 - 2y^2 = +1. Additionary, all friendly number pairs are given. |

Keywords: | friendly number pair Pell equation recursive property of solution sequence positive integer solution |
