Taking the set of natural numbers as the universal set, write down the complements of the following sets:
$\{x: x+5=8\}$
If $A$ and $B$ be any two sets, then $(A \cap B)'$ is equal to
Let $U=\{1,2,3,4,5,6,7,8,9\}, A=\{1,2,3,4\}, B=\{2,4,6,8\}$ and $C=\{3,4,5,6\} .$ Find
$(A \cup B)^{\prime}$
If $A$ and $B$ are two given sets, then $A \cap {(A \cap B)^c}$ is equal to
