1. The problem statement, all variables and given/known data
Reduce the expression to one that just contains xor and/or xnor

2. Relevant equations
(A'B'C')+(A'BC)+(ABC')+(AB'C)

3. The attempt at a solution
C'(A'B'+AB)+C(A'B+AB')
C'(A$\ominus$B)+C(A$\oplus$B)
not really sure what to do next.Do the C' and C cancel each other out?
