幂的运算法则是整式乘除的基础,因此要切实学好、学扎实。学习时应注意以下几点: 一、正确理解幂的各个法则的条件和结论 1.同底数幂相乘的首要条件是“同底”,即相乘的几个幂的底数不论是有理数还是整式的形式,都必须相同才行. The power algorithm is the basis for the multiplication, elimination, and division of the whole formula. Therefore, it must be learned and studied solidly. The following points should be noted when learning: 1. Correctly understand the conditions and conclusions of each power law 1. The first condition that multiplies the power of the base number is “same bottom”, that is, the base of several powers to be multiplied is rational or integer. The forms must all be the same.
