Question

Ktoś wie, jak to rozwiązać? Z góry dziękuję ​

Answer 1

Odpowiedź:

[tex]A=\lbrace5,6,7,8,9,10\rbrace\\B=\lbrace0,2,4,6,8,10,12,14,16,18,20\rbrace\\C=\lbrace5,10,15,20,25,...,50\rbrace\\D=\lbrace10,20,30,40,...,90,100\rbrace\\\\[/tex]

a) [tex]A\cap B=\lbrace6,8,10\rbrace\\[/tex]

b) [tex]A\setminus B=\lbrace5,7,9\rbrace[/tex]

c) [tex]C\cup D=\lbrace5,10,15,20,25,...,50,60,70,80,90,100\rbrace[/tex]

d) [tex]D \setminus C=\lbrace60,70,80,90,100\rbrace[/tex]

e) [tex]A\cap B\cap C=\lbrace5,10\rbrace[/tex]

f) [tex](A\cup B) \cap C=\lbrace5,10,20\rbrace[/tex]

g) [tex](A \setminus D) \cup (C \cap B)=\lbrace5,6,7,8,9,10,20\rbrace[/tex]

h) [tex](C \cap D) \setminus (A \cup B)=\lbrace30,40,50\rbrace[/tex]
