勾股数的发现不得不令人感叹 .a2 +b2 =c2 这一式子能得到多少勾股数呀 ?老师说过 ,勾股数有无限多组 ,那么 ,怎样将它们找出来呢 ?下面让我们先看一例 .　例 1　如表 1 ,第一列中每行的三个数a ,b,c满足abc,试根据表中已有的数的规律 ,试写出当a=2 0时b ,c的值 .表 16,8,1 0 The discovery of the number of Gonads has to be lamentable. How much number of gouaches does this formula have for a2 +b2 = c2? The teacher said that there are an unlimited number of argots, so how do you find them? Let’s look at an example.
