Re: [sympy] Re: MatPow bug or inconsistency?

[Jogi Miglani]

I might had done work on this in #15712
. But in that case i considered
the cases where the determinent of Matrix was zero. Although something can
be changed here

to
meet up the right requirements.

I think for website the issue can be raised at, 
https://github.com/sympy/sympy.github.com/issues
Is it the case that you are not on github?

The point being behavior is inconsistent between ** operator and doit().

In my opinion, it shouldn't happen. Feel free to raise an issue on github for

A while back I was advised to report a SymPy website issue on github. 
The site said it would email me back (to set up a user name), and no 
message came. I don't know if I am the only person with that problem.

I don't have a computer to test but what happens if x is declared as an
integer? For non-integer (or non-real) x the result doesn't necessarily
hold.
