帮你学习幂的运算法则

幂的运算法则包括: 1. am ·an = am+n;2. (am)n = amn;3. (ab)n = an·bn(其中m,n都是正整数).这3条法则是学习整式乘除的基础,学习时应注意以下几点:一、正确理解,把握区别am 就代表a·a·a…am个a,即m个a 相乘的结果.根据幂的概念,很容易理解这3条法则.对于法则1,am·an 代表m个a相乘的结果再与n个a相乘的结果相乘,显然结果共有m+n个a相乘,根据幂的概念,即为am+n.同样,对于法则 2,把(am)n 看作一个幂的形式,则底数为am,指数为n,即代表n个am 相乘的结果.每个am 代表m个a相乘,那么n个am 相乘的结果是什么呢?显然为n·m个a相乘的结果,根…

逆用幂的运算性质解题

幂的运算性质是整式乘除法的重要组成部分,而有些问题的解答中若能巧妙逆用幂的运算性质,可快速解题,使问题得以顺利解答.一、逆用am·an=am n,(am)n=amn例1若am=51,a2n=7,求a3m 4n.分析:根据同底数幂的乘法和幂的乘方的运算性质,先逆用a3m 4n=a3m×a4n,再逆用a3m=(am)3,a4n=(a2n)2,可求出代数式的值.解:∵am=51,a2n=7∴a3m 4n=(am)·3(a2n)2=(15)3×72=14295二、逆用(ab)m=am.bm,am·an=am n例2计算(153)2005×(253)2006.分析:根据积的乘方的运算性质,又513和235互为倒数,先可由同底数幂相乘的逆应用,得(235)2006=(235)2005·(235)=(153)20…
