幂的运算包括“同底数幂的乘法”、“幂的乘方”、“积的乘方”和“同底数幂的除法”.这些法则表解如下:表1法则含义数学表达条件推广注意事项同底数的幂相乘,底数不变,指数相加am×an=am+n底数相同,m,n都是正整数am×an×ap=am+n+p1.a可以是单项式,也可以是多项式2.可逆用幂的 Power operations include “multiplication with base powers”, “powers of power”, “products of power” and “division with base powers”. These rules are illustrated as follows: Table 1 Laws Meanings Mathematical Expression Conditions General Notes Multiplied with the power of the base, the base unchanged, the exponent addition am×an=am+n the same base, m, n are positive integers am×an×ap=am+n+p1.a can be a monomial, it can be Polynomial 2.
