Chúc bạn học tốt!
Lời giải:
a. $D=\left\{4;5;6;7;8;9;10;11;12\right\}$
b. $E=\left\{6;7;8;9;10;11;12;13;14\right\}$
c. $F=\left\{3;4;5;6;7;8;9;10;11\right\}$
d. $F=\left\{30;40;50;60;70;80;90;100;110\right\}$
1/\(A=\left\{21;24;27;30;33;36;39\right\}\)
\(B=\left\{30;35;40\right\}\)
\(C=\left\{32;36;40\right\}\)
2/\(D=\left\{30\right\}\)\(;\)\(E=\left\{40\right\}\)\(;\)\(F=\left\{36\right\}\)
