Let XOR be the eXclusive OR connective
Prove that the associative law applies to XOR I.e., prove that
(P_1 XOR (P_2 XOR P_3)) LEQV ((P_1 XOR P_2) XOR P_3).
- Work out a simple rule to determine exactly when
(P_1 XOR P_2 XOR ... XOR P_n)
is satisfied.
Prove your rule by induction on n.
* Prove that the associative law applies to <->. I.e., prove that
(P_1 <-> (P_2 <-> P_3)) LEQV ((P_1 <-> P_2) <-> P_3).
- Work out a simple rule to determine exactly when
(P_1 <-> P_2 <-> ... <-> P_n)
is satisfied.
