Calculate (leftlangle x^{m} ightangle_{n}) and (leftlangle p^{m} ightangle_{n}) for a particle in a box (an infinitely deep

Calculate \(\left\langle x^{m}\rightangle_{n}\) and \(\left\langle p^{m}\rightangle_{n}\) for a particle in a box (an infinitely deep square well) for arbitrary integers \(n, m>0\). In which limits do we have a classical result?
