If n is a positive integer and ((n^2)+3n-10)/((n^2)+6n-16) is a reduced fracnen, then ((n^2)+3n-10)/((n^2)+6n-16)= . 相关知识点: 试题来源: 解析 8/(11) 由题意知((n^2)+3n-10)/((n^2)+6n-16)=((n-2)(n+5))/((n-2)(n+8))为既约分数,...
个人看法。理解一下The largest integer that must divide n, 表示的是n一定含有的最大的因子，也就是n取最小值时也一定含有的最大因子。n^2=72x，把72分解，n^2=2^3*3^2*x；n是正整数，那么n^2必然要能开方，也就是说x至少含有一个2，n最小值是不是就是2^2*3=12。12最大的因子就是它本身12...
