यदि \(U={1,2,\ldots,16}\), \(A=\{1,2,4,8,16\}\) और \(B=\{3,6,9,12,15\}\), तो (\(A\cup B\)') क्या है?
If \(U={1,2,\ldots,16}\), \(A=\{1,2,4,8,16\}\), and \(B=\{3,6,9,12,15\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
A. ({5,7,10,11,13,14})
Concept
\(A\cup B={1,2,3,4,6,8,9,12,15,16}\). Removing it from (U) leaves ({5,7,10,11,13,14}).
Why this answer is correct
The correct answer is A. ({5,7,10,11,13,14}). \(A\cup B={1,2,3,4,6,8,9,12,15,16}\). Removing it from (U) leaves ({5,7,10,11,13,14}).
Exam Tip
\(A\cup B={1,2,3,4,6,8,9,12,15,16}\) है। (U) से हटाने पर ({5,7,10,11,13,14}) बचता है।
