Well, at least you are getting closer to the right formula,
though I still don't know what ampersand numbersign 8 2 1 1 semi-colon
is. You should use plain text in postings, not Unicode characters.

Okay, so what have you got so far? The only difference between
your posting now and your original posting is that you have fixed
up the ! (factorial indicator). What have you tried in the
meantime, and what problems have you had?
It seems clear that you are working on an assignment, and
the complete program is quite short (61 characters excluding
the function heading) so if we say much at all we would have
given away too much for you to have learned how to do the
assignment for yourself.
