Question

Diketahui: A={x|x>5,x bilangan asli} , b={x|3 ditanya:dengan cara mendaftarkan anggotanya tentukan
A.(A∩B) ∪ (B∩C)
B.(A∪C) ∩ (A∪B)
C.(B∪C) ∩ (A∪C)

Answer 1

Bilangan asli dimulai dari nol sampai seterusnya

Answer 2

A={6,7,8,9,10,...}
B={4,5,6,7}
C={6,7,8,9}

A.(A∩B) ∪ (B∩C) = {6,7} ∪ {6,7} = {6,7}
B.(A∪C) ∩ (A∪B) = {6,7,8,9,10,...} ∩ {4,5,6,7,8,9,10,...} = {4,5,6,7,8,9,10,...}
C.(B∪C) ∩ (A∪C) = {4,5,6,7,8,9} ∩ {6,7,8,9,10,...} = {6,7,8,9}

Maaf kalau misal jwbnnya ada yang salah..
