यदि \(A=\{1,2\}\), \(B=\{3\}\) और \(C=\{4,5\}\) हैं, तो (A\times\(B\times C\)) में कितने अवयव होंगे?

If \(A=\{1,2\}\), \(B=\{3\}\) and \(C=\{4,5\}\), how many elements are in (A\times\(B\times C\))?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

(n\(B\times C\)=1\times2=2), so (n(A\times\(B\times C\))=2\times2=4). Count the inner Cartesian product first.

Step 2

Why this answer is correct

The correct answer is A. (4). (n\(B\times C\)=1\times2=2), so (n(A\times\(B\times C\))=2\times2=4). Count the inner Cartesian product first.

Step 3

Exam Tip

(n\(B\times C\)=1\times2=2), इसलिए (n(A\times\(B\times C\))=2\times2=4)। अंदर का कार्तीय गुणन पहले गिनें।
