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
Correct Answer

A. ({1})

Step 1

Concept
