Dear All,
So far we had pow(2,a+b).expand() -> pow(2,a)*pow(2,b), but
exp(a+b).expand() -> exp(a+b). It will be also nice to have
abs(a*b).expand() -> abs(a)*abs(b) and
log(a*b).expand() -> log(a) + log(b) (for positive a and b, of course).
Thus, I am proposing a patch for this.
Best wishes,
Vladimir
