Step 1 :Define the sets U, A, B, and C as U = {a, b, c, d, e, f, g, h}, A = {a, g, h}, B = {b, g, h}, and C = {b, c, d, e, f}.
Step 2 :Find the complement of set A, denoted as \(A^\prime\), which includes all elements in the universal set U that are not in A. So, \(A^\prime\) = {b, d, f, c, e}.
Step 3 :Find the complement of set C, denoted as \(C^\prime\), which includes all elements in the universal set U that are not in C. So, \(C^\prime\) = {g, h, a}.
Step 4 :Find the union of set B and \(C^\prime\), denoted as \(B \cup C^\prime\), which includes all elements that are in either B or \(C^\prime\), or in both. So, \(B \cup C^\prime\) = {b, h, g, a}.
Step 5 :Find the intersection of \(A^\prime\) and \(B \cup C^\prime\), denoted as \(A^\prime \cap (B \cup C^\prime)\), which includes all elements that are in both \(A^\prime\) and \(B \cup C^\prime\). So, \(A^\prime \cap (B \cup C^\prime)\) = {b}.
Step 6 :Final Answer: \(A^\prime \cap (B \cup C^\prime)\) = \(\boxed{\{b\}}\)
