为什么 1 不能被认为是质数? - 知乎 m = p 1 a 1 p 2 a 2 p 3 a 3 p n a n 什么意思呢? 它表示这样一个结论:对于任意的一个整数,你都能把它因数分解,而且结果是唯一的。 举个例子:1001只能被分解成7×11×13,而且你再也找不到除 (7,11,13)外的一组质数,使它们的乘积是1001。 那么这个定理有什么用呢?
What is the value of $1^i$? - Mathematics Stack Exchange There are infinitely many possible values for $1^i$, corresponding to different branches of the complex logarithm The confusing point here is that the formula $1^x = 1$ is not part of the definition of complex exponentiation, although it is an immediate consequence of the definition of natural number exponentiation
