यदि \(A=\{1,4,9,16,25\}\) और \(B=\{2,4,8,16,32\}\), तो \((A-B)\cup(B-A)\) क्या है?
If \(A=\{1,4,9,16,25\}\) and \(B=\{2,4,8,16,32\}\), what is \((A-B)\cup(B-A)\)?
Explanation opens after your attempt
B. ( {1,2,8,9,25,32} )
Concept
(A-B={1,9,25}) and (B-A={2,8,32}). Their union is ({1,2,8,9,25,32}).
Why this answer is correct
The correct answer is B. ( {1,2,8,9,25,32} ). (A-B={1,9,25}) and (B-A={2,8,32}). Their union is ({1,2,8,9,25,32}).
Exam Tip
(A-B={1,9,25}) और (B-A={2,8,32}) है। दोनों का संघ ({1,2,8,9,25,32}) है।
