Cho \(A = \left\{ {0;2;4;6;8;10} \right\}\), \(B = \left\{ {0;1;2;3;4;5;6} \right\}\) và \(C = \left\{ {4;5;6;7;8;9;10} \right\}\). Hãy tìm
a. \(A \cap \left( {B \cap C} \right)\)
b. \(A \cup \left( {B \cup C} \right)\)
c. \(A \cap \left( {B \cup C} \right)\)
d.\(\left( {A \cup B} \right) \cap C\)
e. \(\left( {A \cap B} \right) \cup C\)
a. \(A \cap \left( {B \cap C} \right) = \left\{ {4;6} \right\}\)

b. \(A \cup \left( {B \cup C} \right) = \left\{ {0;1;2;3;4;5;6;7;8;9;10} \right\}\)
c. \(A \cap \left( {B \cup C} \right) = A\)
d. \(A \cup B = \left\{ {0;1;2;3;4;5;6;8;10} \right\}\)
Vậy \(\left( {A \cup B} \right) \cap C = \left\{ {4;5;6;8;10} \right\}\)
e. \(A \cap B = \left\{ {0;2;4;6} \right\}\)
Vậy \(\left( {A \cap B} \right) \cup C = \left\{ {0;2;4;5;6;7;8;9;10} \right\}\)
