一、单项式乘以单项式几个单项式相乘时,按以下三点要求,求出它们的乘积:(1)乘积的系数等于各单项式系数的乘积;(2)用各个单项式中相同字母的指数和作为乘积里这个字母的指数;(3)只在一个单项式里含有的字母,应连同它的指数写在乘积里.
1. When multiplying a monomial by a monomial with a few terms, multiply the following three requirements and find their product: (1) the product’s coefficient is equal to the product of the individual term coefficients; (2) uses the same letter’s index for each individual term and As an index of the letter in the product; (3) The letter contained in only a monomial should be written in the product along with its index.
