单项式除以单项式和多项式除以单项式,是整式除法中的两个知识重点,必须认真学习它.学好它的关键是:理解和掌握两个重要的运算法则:一、单项式除以单项式法则:单项式相除,把系数、同底数幂分别相除,作为商的因式,对于只在被除式里含有的字母,则连同它的指数作为商的一个因式.理 The monomial divided by the monomial and the polynomial divided by the monomial is the two focus of knowledge in the division of whole formulas. It must be carefully studied. The key to learning it is to understand and master two important algorithms: 1. The monomial divided by the monomials: monomials Divide, divide the coefficient and the power of the base separately, as the quotient factor of the quotient, and for the letter contained only in the divided quotient, together with its exponent as a factor of the quotient.
