昨天刚看见的数学趣题,是我近期见过的最有意思的了!大家可以尽管尝试一下,数学方法或者写程序暴力算都行~ 保证解是存在的。
解法见这个链接,不过最好先自己想想,实在不行了再点开看,否则会丧失乐趣:https://www.quora.com/How-do-you-find-the-positive-integer-solutions-to-frac-x-y+z-+-frac-y-z+x-+-frac-z-x+y-4
Did you know you can write your own about section just like this one? It's really easy. Head into the the Traction Options menu and check out the footer section. Type some stuff in the box, click save, and your new about section shows up in the footer.

惊了,看上去这么naive的配图,解了我一晚上也没解出来。。。虽然从可开平方的有理数解中隐约感觉到了椭圆曲线的召唤。。。
恐怕放在国内一流大学能解的人是也少之又少。。。除非之前做过
emmm有点高深,似乎打开了新世界。
另外,解释全英文的???我的学历表示看不懂~博主有中文版的么【捂脸】
被坑大了!龙哥被反杀!
