我们都知道,幂的乘法运算包括同底数幂的乘法、幂的乘方、积的乘方,其运算法则的表达式分别为:a~m·a~n=a~(m+n),(a~m)~n=a~(mn),(ab)~n=a~nb~n(m、n为正整数).在解题过程中,根据算式的结构特征,巧妙逆用这几个法则,常可以化繁为简,化难为易,使很多棘手的问题迎刃而解.
We all know that the multiplication of a power consists of the multiplication of the power of the base, the power of the power, the power of the product, and the expressions of its algorithm are: a~m a~n=a~(m+n), (a~m)~n=a~(mn),(ab)~n=a~nb~n(m,n is a positive integer). In the solving process, according to the structural characteristics of the formula, it is used ingeniously to reverse this A few rules can often be simplified and simplified, and it is difficult to make it easier to solve many difficult problems.
