Question

No 20 dan 19 ye mke cara !!

Answer 1

19. A = {4,8,12,16,20,24}
      B = {3,6,9,12,15,18,21,24}
      A∩B = {12,24}
      A∪B = {3,4,6,8,9,12,15,16,18,20,21,24}

20. S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14}
      A = {2,3,5,7,11,13}
      B = {1,3,5,7,9,11,13}
      
    komplemen(A∪B)= S-(A∪B)
                                = {1,2,3,4,5,6,7,8,9,10,11,12,13,14}-{1,2,3,5,7,9,11,13}
                                = {4,6,8,10,12,14)
