यदि \(A=\{1,2,4,8,16\}\), \(B=\{1,3,9,27\}\) और \(C=\{1,5,25\}\), तो (\(A\cap B\)\cup\(B\cap C\)\cup\(C\cap A\)) क्या है?
If \(A=\{1,2,4,8,16\}\), \(B=\{1,3,9,27\}\), and \(C=\{1,5,25\}\), what is (\(A\cap B\)\cup\(B\cap C\)\cup\(C\cap A\))?
Explanation opens after your attempt
A. ({1})
Concept
The only common element in each pair of sets is (1). Hence the union of all pairwise intersections is ({1}).
Why this answer is correct
