利用对称数据的统计信息

〚新思路7下-14.1(1)-12〛内线不等式☆💯 〚2024.07.21〛内线2⭐⭐💯

对称意味着:左右重复——※左右问题

〚新思路8上-16.1(2)-13〛根式求值💯⭐

对称问题,常可以定义特性,以简化分析

  1. 比如,a、b对称出现,那么不妨设a>b 〚250912〛⭐⭐🙇

    Divide the ten numbers l,2,3..,9,10 into 5 groups randomly, each group has 2 numbers.If the two numbers of a group are a and b, then calculate the value of algebraic expression . This value is called the value of this group. Then we can get 5 values. What is the maximum sum of these five values? What is the minimum sum? What is the minmum and maximum sum if the expression is 关联:代数式-整式、分析-局部与整体、对称思想、※返璞归真 年级:7年级
