陆彬怡对寻找隐含条件有自己的高招,同学们有什么高招?也来展示一下吧.上学期,我们第一次接触到题目中的隐含条件,比如几何图形中的邻补角互补,对顶角相等等.上周一开始学算术平方根,没想到算术平方根中也有隐含条件,这条件作用可大呢.不信?你瞧!例1已知|2 004-a|+(a-2 005)~(1/2)=a,求a-2 004~2的值.解析:本题初看似乎无从下手,但想到 Lu Binyi look for the implied conditions have their own tricks, what are the good ideas students? Also to show it. Last semester, we first exposed to the implicit conditions in the subject, such as geometric figures complement each other complementary, The vertex angle is equal, etc. Starting from the arithmetic square root last Monday, I did not expect the arithmetic root-meanings to have implied conditions. This condition can play a big role. Do you not believe it? Example 1 Known | 2 004-a | + (a-2 005) ~ (1/2) = a, find the value of a-2 004 ~ 2.
