Generate explicit formula for mth derivative

I'd like to generate an explicit formula for the mth derivative of x^n, for example:

diff( x^n, x $ m )

The result in MuPad is d^m/dx^m( x^n ), but I want MuPad to write the explicit formula (which I believe is n!/(n-m)! x^(n-m))

Answer 1

You can't.

Answer 2

[Walter Roberson]

The older Maple symbolic engine can do this, yielding pochhammer(n-m+1, m)*x^(n-m)

I do not have access to MuPAD to test with.
