一、因数分解的唯一性例1 解方程:62x+4=2x+8·33x.解原方程即22x+4·32x+4=2x+8·33x.因2、3均为质数,由因数分解的唯一性,应有
First, the uniqueness of factorization Example 1 Solution equation: 62x+4=2x+8·33x. The original solution equation is 22x+4·32x+4=2x+8·33x. Since both 2, 3 are prime numbers, the factors are The uniqueness of the decomposition should be
