1.一个重要不等式大家一定熟悉以下著名的重要不等式:若a,b,c∈R+,则a~3+b~3+c~3≥3abc(1)当且仅当a=b=c等号成立.2.一种论证过程有关这个不等式的证明方法较多,其中一种基本且有效的方法就是因式分解与凑配有机结合,其推理过程如下: 1. An Important Inequality We must all be familiar with the following notable important inequalities: a, b, c, c, and c ≥ 3abc if and only if a = b = c, etc. No. 2. A proof of the inequality of the proof of this method is more, one of the basic and effective method is the combination of factorization and reorganization, the reasoning process is as follows:
