Homework Statement
[A,B] = C and operators A,B,C are all hermitian show that C=0
Homework Equations
The Attempt at a Solution
Since it is given that all operators are hermitian I know that A=A' B=B' and C=C' so i expanded it out to
AB-BA=C
A'B'-B'A'=C
(BA)' - (AB)'=C
I'm not real sure where I am supposed to go or what properties of hermitian operators I am supposed to used to show that AB=BA..any help would be appreciated thank
