Understanding the Problem

To find the set ${$ (A \cap C)^{\prime}$}$, we first need to understand the given information and the operations involved. The universal set $U$ is defined as $\{1,2,3,4,5,6,7,8\}$ , and two subsets $A$ and $C$ are given as $A=\{1,3,4,8\}$ and $C=\{1,2,4,5,8\}$ , respectively.

Intersection of Sets

The intersection of two sets $A$ and $C$ , denoted as $A \cap C$ , is the set of elements that are common to both sets. In this case, the intersection of $A$ and $C$ is $\{1,4,8\}$ .

Complement of a Set

The complement of a set $S$ , denoted as $S^{\prime}$ , is the set of elements that are in the universal set $U$ but not in $S$ . To find the complement of $A \cap C$ , we need to find the elements that are in $U$ but not in $\{1,4,8\}$ .

Finding the Complement of $A \cap C$

The complement of $A \cap C$ is the set of elements that are in $U$ but not in $\{1,4,8\}$ . Therefore, we need to find the elements that are in $U$ but not in $\{1,4,8\}$ . The elements in $U$ but not in $\{1,4,8\}$ are $\{2,3,5,6,7\}$ .

Conclusion

Therefore, the set ${$ (A \cap C)^{\prime}$}$ is $\{2,3,5,6,7\}$ .

Final Answer

The final answer is $\boxed{\{2,3,5,6,7\}}$ .
