一个不等式猜想的上界

Upper bound for the conjecture of an inequality

在文献[2]中给出了不等式nan-xn≥a-xt,(a>0,λ>0,n∈N={1,2,…},0≤x≤λ<a)的推广形式和下界估计,我们使用极值的方法进一步得到该不等式的最佳上界估计.

In literature [ 2 ], the general form and lower bound of the inequalty n√a^n-x^n≥a-xt （ a 〉0, λ 〉 0, n ∈N = { 1,2,…},0 ≤x≤λ 〈 a）were given. In this paper, we obtain the best upper bound of this inequality using the extremum method.
