यदि \(A=\{1,2\}\), \(B=\{3,4\}\) और \(C=\{5,6\}\) हैं, तो (A\times\(B\cup C\)) में कितने अवयव होंगे?
If \(A=\{1,2\}\), \(B=\{3,4\}\) and \(C=\{5,6\}\), how many elements are in (A\times\(B\cup C\))?
Explanation opens after your attempt
A. (8)
Concept
\(B\cup C={3,4,5,6}\), so (n(A\times\(B\cup C\))=2\times4=8). Complete the set operation first.
Why this answer is correct
The correct answer is A. (8). \(B\cup C={3,4,5,6}\), so (n(A\times\(B\cup C\))=2\times4=8). Complete the set operation first.
Exam Tip
\(B\cup C={3,4,5,6}\), इसलिए (n(A\times\(B\cup C\))=2\times4=8)। पहले समुच्चय संक्रिया पूरी करें।
