A

x\notin\,A\;\implies\;x\in\,Ax∈

/

A⟹x∈A

\text{To prove: $\bf(A{\cup}B)'=A'{\cap}B'$}To prove: (A∪B)

=A

∩B

\text{Let\,$x\in(A{\cup}B)'$}Letx∈(A∪B)

\iff\;x\notin\,A{\cup}B⟺x∈

/

A∪B

\iff\;x\notin\,A\;\&\;x\notin\,B⟺x∈

/

A&x∈

/

B

\iff\;x\in\,A'\;\&\;x\in\,B'⟺x∈A

&x∈B

\iff\;x\in\,A'{\cap}B'⟺x∈A

∩B

\therefore\boxed{\bf(A{\cup}B)'=A'{\cap}B'}∴

(A∪B)

=A

∩B
