यदि \(A=\{1,2,3,4\}\) है, तो (\mathcal{P}(A)) में कुल कितने तत्व होंगे?
If \(A=\{1,2,3,4\}\), how many elements will (\mathcal{P}(A)) have?

Correct Answer
C. (16)
Concept
If a set has (n) elements, its power set has \(2^n\) elements. Here \(2^4=16\), so remember this rule.
Why this answer is correct
The correct answer is C. (16). If a set has (n) elements, its power set has \(2^n\) elements. Here \(2^4=16\), so remember this rule.
Exam Tip
यदि समुच्चय में (n) तत्व हों, तो घात समुच्चय में \(2^n\) तत्व होते हैं। यहां \(2^4=16\), इसलिए यह नियम याद रखें।
