Step 1 :The universal set U is \(U = \{1, 2, 3, 4, 5, 6, 7\}\)
Step 2 :Set A is \(A = \{1, 3, 5, 7\}\)
Step 3 :Set B is \(B = \{2, 5, 7\}\)
Step 4 :The complement of set A, denoted by A', is the set of all elements in the universal set U that are not in A. So, \(A' = \{2, 4, 6\}\)
Step 5 :The complement of set B, denoted by B', is the set of all elements in the universal set U that are not in B. So, \(B' = \{1, 3, 4, 6\}\)
Step 6 :The intersection of two sets, denoted by ∩, is the set of all elements that are common to both sets. So, the intersection of the complements of sets A and B is \(A' \cap B' = \{4, 6\}\)
Step 7 :Final Answer: \(\boxed{\{4, 6\}}\)
