二次根式的化简求值是中学数学中培养学生的计算能力的一个极为重要的内容,但一般来说运算都比较繁复,在解答过程中,若能够根据要化简求值表达式的特点,巧妙综合运用所学的知识,可化繁为简,达巧夺天工之妙,本文介绍一些根据题目本身的特点解此类问题的方
The secondary rooted simplifying evaluation is an extremely important content in cultivating students’ computational ability in middle school mathematics. However, in general, the calculations are complicated. In the process of solving, if we can simplify the evaluation of the expressions , Ingeniously applying the learned knowledge in an ingenious way, you can simplify the process and achieve the best of heaven. This article describes some aspects of solving such problems based on the characteristics of the topic itself.
