中文摘要:幂指不等式在数学竞赛中时有出现 ,其证明往往是比较困难的 .本文借助于新的分析技巧给出了一个新颖的幂指不等式 (即任给两个正数a和b,有aa+bb 不小于ab+ba)及其推广形式 。
外文摘要:Power exponent inequality often appeared in Mathematical Olympian, its proof was usually rather difficult.By virture of some new techniques of analysis,a novel power exponent inequality was given(If a and b are arbitrary two posstive numbers,then a a+b b was no less than a b+b a),so was its extend.The results can also be applied to a Mathematical Olympian problem.
