Answer 1

2.

\(E=\left\{-3;-2;-1;0;1;2;3\right\}\)

\(A=\left\{-2;0;2\right\}\)

\(B=\left\{-1;0;1;2;3\right\}\)

\(A\cap B=\left\{0;2\right\}\)

\(A\cup B=\left\{-2;-1;0;1;2;3\right\}\)

\(C_EA=\left\{-3;-1;1;3\right\}\)

\(C_EB=\left\{-3;-2\right\}\)

3.

\(A=\left\{0;1;2;3;4\right\}\)

\(B=\left\{1;3;9;27\right\}\)

\(A\cap B=\left\{1\right\}\)

\(A\cup B=\left\{0;1;2;3;4;9;27\right\}\)

\(A\backslash B=\left\{0;2;3;4\right\}\)

\(B\backslash A=\left\{3;9;27\right\}\)
