i'm just not sure on this little detail, and its keeping me from finishing this problem.

take the arbitrary operator [tex]\tilde{p}^{n}\tilde{y}^{m}[/tex] where p is the momentum operator , and x is the x position operator

the expectation value is then <[tex]\tilde{p}^{n}\tilde{y}^{m}[/tex] >

is this the same as <[tex]\tilde{p}^{n}[/tex]> <[tex]\tilde{y}^{m}[/tex]>?

if not, how would i go about calculating <[tex]\tilde{p}^{n}\tilde{y}^{m}[/tex] >?
