Please see the attached file for the fully formatted problems.

Verify DeMorgan's laws (equation 1 and 2 below) using truth tables.

Prove the generalized DeMorgan's laws:

(1) (NOT(p1 p2 .... pk))

(2) (NOT(p1+p2+...+pk))

by induction on k, using the basic laws:

NOT(pq)

NOT(p+q)

Then, justify the generalized laws informally by describing what 2k row truth tables for each expression and their subexpressions look like.
