幂的运算性质是整式乘除法的基础,熟练地运用幂运算性质进行幂的运算,对整个初中阶段的数与式的运算及代数式的恒等变形能力将产生较大的影响。一、正确理解幂的运算性质的条件和结论 1.同底数幂相乘,其条件是“同底”,即幂的底数,不论是“数”还是“式”都必须相同才行。运算结果是一个与 The power of the power is the basis of the multiplication and division of the whole formula. Proficient in the use of the exponentiation of the exponentiation operation will have a greater impact on the operation of the number and formula of the entire junior middle stage and the ability of the algebraic type of constant deformation. First, the correct understanding of the power of the nature of the conditions and conclusions 1. Multiplied with the base number of power, the condition is “same bottom”, the power of the base number, whether it is “number” or “style” must be the same Caixing. The result of the operation is an
