对数是数学代数中重要的组成部分，对数是对求幂的逆运算，对数的一般形式为x=logₐN（a>0，且a≠1），其中a叫做对数的底数，N叫做真数。 使用对数计算器，我们只需输入对数的底数和真数，即可快速计算出对数，节约人工运算时间，提升对数的运算效率，为 ...

简单来说，如果a的b次幂等于n（即a^b = n），那么b就是以a为底n的对数，记作log a n。 要计算对数，我们需要知道三个要素：底数、真数和对数。 底数是对数运算中的基数，真数是幂运算的结果，而对数则是我们要求解的指数。

The problem is that \log z is multivalued, and so requires a branch cut. \log z=\log|z|+i\,\text{arg}\,z. We can choose the branch -\pi<\text{arg}\,z\le\pi. Now, let z=e^{\frac{3\pi i}4}. \log z=\log e^{3\pi i/4}=\frac{3\pi i}4. ...
