所谓夹逼法,就是先确定某个待求元素的取值范围,然后在此范围内夹逼出相应结果的方法.其夹逼的主要方式有:由 a≤p≤b 夹逼出为某些数值;由 A≤B 且 A≥B 夹逼出 A=B.这种夹逼法对解与整数有关的问题有独特的奇效.一解与根式或方程有关的问题例1 若 m 适合关系式
The so-called clamping force method is to determine the range of values of a certain element to be sought, and then press the corresponding results in this range. The main methods of clamping force are: a ≤ p ≤ b clamp to force a certain These values are: A = B with A ≤ B and A ≥ B. This clamp method has unique quirks for solving integer-related problems. A solution to problems related to root equations or equations Example 1 if m fits formula
