Question

Diketahui A={x|x>5,x bilangan asli}
B={x|5 C={x|5
A. Cara pembacaanya serta jawabannya, seperti misalnya A={|blablabla} jawabannya A={3,4,blablabla) misalnya
B. (A Π B) U (BΠC)
C. (AUC)Π(AUB)
D.(BUC)Π(AUC)

Answer 1

A. A = bilangan asli yg lebih dari 5
   A = {6, 7, 8, 9, 10, 11, 12, 13....}
   B = bilangan asli antara 3 dan 8
   B = {4, 5, 6, 7}
   C = bilangan asli antara 5 dan 10
   C = {6, 7, 8, 9}

b.  A n B = {6, 7}
     B n C = {6, 7}
   (A n B) u (B n C) = {6, 7}

c.  A u C = {6, 7, 8, 9, 10, 11, 12, 13...}
     A u B = {4, 5, 6, 7, 8, 9, 10, 11, 12, 13...}
     (A u C) u (A u B) = {6, 7, 8, 9, 10, 11, 12, 13]

d.  B u C = {4, 5, 6, 7, 8, 9}
     A u C = {6, 7, 8, 9, 10, 11, 2, 13...}
     (B u C) n (A n C) = {6, 7, 8, 9}

maaf kalau ada yg salah
