Show the validity of the logical equivalence: -(p <> q) = ¬p <→ q

Are the two logical statements equivalent -p-->q q-->-p

(d) Show that [av (a Ab)]A¬b¬(a V b) by using logical equivalence identities.

Determine if each statement below is true or false, and explain your reasoning.a) If two statements are logically equivalent, then so are their negations. b) If the statement p is a contradiction, then, for any statement q , the statement p -> q is a tautology. c) State the type of relation the statement, x2 = xy is? Discuss your answer.
