The logically equivalent proposition of `phArrq` is `(p^^q)vv(p^^q)` b. `(p=>q)^^(p=>q)` c. `(p^^q)vv(p=>q)` d. `(p^^q)(pvvq)`

The logically equivalent proposition of phArrq is a. (p^^q)vv(p^^q) b. (p=>q)^^(q=>p) c. (p^^q)vv(p=>q) d. (p^^q)(pvvq)

The logically equivalent proposition of p hArr q is (p^^q)vv(p^^q) b.(p rArr q)^^(p rArr q) c.(p^^q)vv(p rArr q) d.(p^^q)o+(p vv q)

(p^^~q)vv(~p^^q) is :

(p ^^ q) vv (~q ^^ p) -=

(p ^^ q) vv (~q ^^ p) -=

The proposition S : (p rArr q) iff (~p vv q) is a

If p, q are two propositions then (p vv ~q)^^( ~p^^q) is

(p ^^ ~q) ^^ (~p vv q) is
