1.提出问题合肥一中高三某学年度有这样一道耐人寻味的段考题,题目如下:题1已知a>0,b>0,且a+b=4,求y=(a+2/a)(b+2/b)的最小值.2.解法探究该题是条件函数最值问题,一看此题,笔者首先想到的是将待求式展开,再对展开式进行两次不等变换.具体方法如下: 1. Ask a Question Hefei a middle school senior high school year such an interesting section of the exam questions are as follows: Question 1 known a> 0, b> 0, and a + b = 4, seeking y = (a +2 / a ) (b + 2 / b) .2. Solution to explore the problem is the most value of the conditional function problem, a look at this question, the author first thought is to be unfolded, and then expanded twice Transform. Specific methods are as follows:
