(p longleftrightarrow q)-=...

Let (p to q) leftrightarrow (~q**p) is a tautology , then p**~q is equivalent to

The p^(th) term T_(p) of H.P is q(p+q) and q^(th) term T_(q) is p(p+q). Prove that T_(p+q)=pq

Show that ~(p harr q) -= ( p ^^ ~q) vv(~p ^^q) .

Show that ~(p harr q) -= ( p ^^ ~q) vv(~p ^^q) .

Show that ~(p harr q) -= ( p ^^ ~q) vv(~p ^^q) .

P ** q = p^2 - q^2 p $ q = p^2 - q^2 p $ q = p^2 + q^2 p @ q = pq + p + q p Delta q = Remainder of p/q p © q = greatest integer less than or equal to p/q . If p = 8 and q = 10 , then the value of [(p $ q) Delta (p @ q)] ** [(q ** p) @ (q © p)] is :

P ** q = p^2 - q^2 p % q = p^2 - q^2 p $ q = p^2 + q^2 p @ q = pq + p + q p Delta q = Remainder of p/q p © q = greatest integer less than or equal to p/q . If p = 11 and q = 7 , then the value of (p ** q) @ (p $ q) is:

The statement which is not a tautology is (p harr q)[(p rarr q)^^(q rarr q)] b.(p rarr q)vv(sim p rarr q) c.(p^^q)rarr(p vv q)d(p^^q)vv[(p vv q)rarr-q]
