Collect factors with negative power

Question

Hi, when I try to collect all powers, but I have a negative power from the product, then collect_factors doesn't work. Applying expand_power before that has no effect either.

for example:

collect_factors($a b c (a b c)**(-1)$);

is not equel 1, but still abc (abc)**(-1).

Answer 1

Thanks, this is an issue with expand_power not taking care of negative powers. Will fix.

Answer 2

Now fixed in 2.4.3.
