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

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

Explanation opens after your attempt
Correct Answer

D. (64)

Step 1

Concept

(n\(A\times B\)=3\cdot2=6), so (n(P\(A\times B\))=26=64). Use \(2^n\) for a power set.

Step 2

Why this answer is correct

The correct answer is D. (64). (n\(A\times B\)=3\cdot2=6), so (n(P\(A\times B\))=26=64). Use \(2^n\) for a power set.

Step 3

Exam Tip

(n\(A\times B\)=3\cdot2=6), इसलिए (n(P\(A\times B\))=26=64)। घात समुच्चय के लिए \(2^n\) लगाएं।
