Question: Verify (valid or not valid) using resolution the following logical consequence: F1 = xP(x,x) F2 = xyz((P(x,y)P(y,z))P(z,x)) F3 = xy(P(x,y)P(y,x)) F1F2 F3

Verify (valid or not valid) using resolution the following logical consequence:

F1 = xP(x,x)

F2 = xyz((P(x,y)P(y,z))P(z,x))

F3 = xy(P(x,y)P(y,x))
