无理不等式的证明问题经常出现在国内外各级各类数学竞赛及各种数学期刊的“数学问题”中,证明无理不等式虽然方法灵活多变、因题而异,但总以一定的转化为基础,通过转化简化问题,沟通与已知不等式之间的联系,使问题获解.可以说,证明无理不等式的过程是一个恰到好处的转化过程.为此,本 Proof of irrational inequality often appears in various mathematical competitions at home and abroad and various mathematical journals “mathematical problems ”, prove irrational inequality Although the method is flexible, due to the problem, but always with a certain degree of conversion As the basis for solving the problem by transforming the problem of simplification, communication and known inequality, it can be said that the process of proving the irrational inequality is a proper transformation process.Therefore,
