If |P(AxA)| = 16 then |A|=4. - ANSFalse The statement P : for all integers "x", x>0 implies x^2 ≥ 0 is trivially true. - ANSTrue Let a,b,c,d,n be integers. If a+b congruent to c (mod n) and a+d congruent to c (mod n), then b is congruent to d (mod n). - ANSTrue Let n be an integer where n is congruent to 1 mod 4. Then n^12 is congruent to 1 mod 16 - ANSTrue Let P,Q,R be statements. Then Pˇ(QˆR)=(¬(Pˆ¬Q))ˆ(PˇR) -...
