Đáp án:
a.$\{0,1,3,5,7,9\}$
b.$\{-2,-1,0,1,2,7,9\}$
c.$\varnothing$
d.$\varnothing$
Giải thích các bước giải:
a.Ta có:
$C\cap D=\{0,1\}$
$\to (C\cap D)\cup E=\{0,1\}\cup\{1,3,5,7,9\}=\{0,1,3,5,7,9\}$
b.Ta có:
$E\setminus D=\{7,9\}$
$\to (E\setminus D)\cup C=\{7,9\}\cup \{-2,-1,0,1,2\}=\{-2,-1,0,1,2,7,9\}$
c.Ta có:
$C\cap E=\{1\}$
$\to (C\cap E)\setminus D=\varnothing$
d.Ta có:
$D\cap C=\{0,1\}$
$C\cup E=\{-2,-1,0,1,2,3,5,7,9\}$
$\to (D\cap C)\setminus(C\cup E)=\varnothing$
