The logical statement `[~(~pvvq)vv(p^^r)]^^(~q^^r)` is equivalent to (a) `(~p^^~q)^^r` (b) `~p vv r` (c) `(p^^r)^^~q` (d) `(p^^~q)vvr`

(~(pvvq))vv(~p^^q) is logically equivalent to

(~(pvvq))vv(~p^^q) is logically equivalent to

(~(pvvq))vv(~p^^q) is logically equivalent to

((p^^q)vv(pvv~q))^^(~p^^~q)) is equivalent to (A) ~p^^~q (B) p^^~q (C) pvv~q (D) ~pvvq

Let p, q, r be three statements. Then, ~(pvv(q^^r)) is equal to a) (~p^^~q)^^(-p^^r) b) (~pvv~q)^^(~pvv~r) c) (~p^^~q)vv(~p^^~r) d) (~pvv~q)vv(~p^^~r)

The logically equivalent statement of (p ^^ q) vv ( p ^^r) is

The dual of the statement ~( p vv q) ^^ [p vv(q ^^ ~r)] is
