यदि \(A=\{1,2\}\), \(B=\{3,4,5\}\) और \(C=\{6,7,8\}\) हैं, तो (|\(A\times B\)\times C|) क्या है?

If \(A=\{1,2\}\), \(B=\{3,4,5\}\), and \(C=\{6,7,8\}\), what is (|\(A\times B\)\times C|)?

Explanation opens after your attempt
Correct Answer

C. (18)

Step 1

Concept

\(|A\times B|=2\cdot3=6\), and then \(6\cdot3=18\). Cardinality also multiplies in nested products.

Step 2

Why this answer is correct

The correct answer is C. (18). \(|A\times B|=2\cdot3=6\), and then \(6\cdot3=18\). Cardinality also multiplies in nested products.

Step 3

Exam Tip

\(|A\times B|=2\cdot3=6\) और फिर \(6\cdot3=18\)। नेस्टेड गुणनफल में भी कार्डिनलिटी गुणा होती है।
