幂的运算法则是学习整式乘除的基础,在进行幂的运算时,有些地方容易出错,要特别注意,有些运算要注意技巧,力求简便.一、注意正确理解幂的运算法则对于整数m、n,幂的运算有如下法则:1am·an=am+n,2(am)n=amn,3(ab)m=ambm,4am÷an=am-n(a≠0).学习时,要能熟练地将每条法则翻译成文字语言,如法则1可叙述为“同底数的幂相乘,底数不变,指数相
Exponentiation algorithm is the basis for learning integer multiplication and division, in the power of the operation, some places prone to error, pay special attention to, some operations should pay attention to skills, and strive to be simple. First, pay attention to the correct understanding of the power of the algorithm For the integer m, n , The operation of the power has the following rules: 1 am.an=am + n 2 (am) n = amn, 3 (ab) m = ambm, 4am ÷ an = am-n Skilled to translate each law into a literal language, such as law 1 can be described as ”multiplied by the power of the same base, the base constant, the exponential phase
