1:
\(A=\left\{0;1;2;4\right\};B=\left\{0;2;3;5;7\right\}\)
\(A\cap B=\left\{0;2\right\}\)
\(A\cup B=\left\{0;1;2;4;3;5;7\right\}\)
\(A\text{B}=\left\{1;4\right\}\)
\(B\text{A}=\left\{3;5;7\right\}\)
2: \(A\text{B}=\left\{1;4\right\}\)
\(A=\left\{0;1;2;4\right\}\)
=>(A\B)\(\subset\)A
A\(A\B)
={0;1;2;4}\{1;4}
={0;2}
=\(A\cap B\)
a: \(A\cap B=\varnothing\)
\(A\cup B=\left[-2;7\right]\)
A\B=[-2;0]
B\A=[1;7]
a: \(A\cap B=\left[2;3\right]\)
\(A\cup B=\left(-\infty;+\infty\right)\)
b: \(\left(A\cup B\right)\cap C=\left(0;4\right)\)
\(1,\\ a,X=\left\{3;4\right\};\left\{2;3;4\right\};\left\{1;2;3;4\right\}\\ b,X=\left\{2;4\right\}\\ X=\left\{2\right\}\\ X=\left\{4\right\}\\ X=\varnothing\)
\(2,\\ a,A=\left\{-3;-2;0;1;2;3;4\right\}\\ B=\left\{0;1;2;3;4;6;9;10\right\}\\ b,A=\left\{1;2;3;4;5\right\}\\ B=\left\{1;2;3;6;9\right\}\)
