WebbAdd a comment. 3. CNF-SAT is in NP since you can verify a satisfying assignment in polynomial time. CNF-SAT is NP-hard since SAT is a special case of CNF-SAT, and so we can reduce the NP-hard problem SAT to the CNF-SAT. Since it is both in NP and NP-hard, we conclude that CNF-SAT is NP-complete.
