摘要
将“n个正数的算术平均数大于等于几何平均数”这一重要不等式推广到“加权算术平均值的函数与函数值的加权算术平均值之间的关系”,继而得出结论“n个正数的加权算术平均数不小于它们的加权几何平均数”.
Based on the arithmetic average of the numbers the set ( a1 ,a2,…,an) are all greater than O) , a conclusion am divided by “n” is greater than or equals to the “n”th root is not less than its geometric average (the numbers in can be drawn as the sum of the products n1 a1 to nm of the products of the a1^n1 to am^nm.
