यदि \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\) और \(C=\{4,6,8\}\) हैं, तो (|A\times\(B\cup C\)|) क्या है?
If \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\), and \(C=\{4,6,8\}\), what is (|A\times\(B\cup C\)|)?
Explanation opens after your attempt
C. (16)
Concept
\(B\cup C={2,4,6,8}\), so (|A\times\(B\cup C\)|=4\cdot4=16). Find the union first.
Why this answer is correct
The correct answer is C. (16). \(B\cup C={2,4,6,8}\), so (|A\times\(B\cup C\)|=4\cdot4=16). Find the union first.
Exam Tip
\(B\cup C={2,4,6,8}\), इसलिए (|A\times\(B\cup C\)|=4\cdot4=16)। पहले संघ निकालें।
