यदि \(A=\{1,2\}\), \(B=\{3,4\}\) और \(C=\{5\}\), तो (A\times\(B\cup C\)) किसके बराबर है?
If \(A=\{1,2\}\), \(B=\{3,4\}\), and \(C=\{5\}\), then (A\times\(B\cup C\)) equals which expression?
Explanation opens after your attempt
Correct Answer
A. (\(A\times B\)\cup\(A\times C\))
Concept
Cartesian product distributes over union in the second component. Remember (A\times\(B\cup C\)=\(A\times B\)\cup\(A\times C\)).
Why this answer is correct
The correct answer is A. (\(A\times B\)\cup\(A\times C\)). Cartesian product distributes over union in the second component. Remember (A\times\(B\cup C\)=\(A\times B\)\cup\(A\times C\)).
Exam Tip
कार्तीय गुणन दूसरे घटक में संघ पर वितरित होता है। सूत्र (A\times\(B\cup C\)=\(A\times B\)\cup\(A\times C\)) याद रखें।
