整式的乘除是 本章的重点,而幂的运算是整式乘除的基础,熟练地运用幂的运算性质进行幂运算,对今后与之相关的数与式运算,代数式的恒等变形等有着深远的影响。 The multiplication and division of integer formulas is the focus of this chapter, and the power calculation is the basis of the multiplication and division of the whole formula. Proficient in the use of the power of the nature of the operation of the exponentiation operation, has a far-reaching impact on the mathematical and mathematical operations associated with it in the future, algebraic type of constant deformation .
