### logexpand

Run Example
```(%i1)logexpand:all;
(%o1)                                 all
(%i2) log(3*x);
(%o2)                           log(x) + log(3)
(%i3) ```
Run Example
```f(x) := log(1+x);
(%o1)                         f(x) := log(1 + x)
(%i2) logexpand:all;
(%o2)                                 all
