यदि (A) में (4) सदस्य हैं, तो (\mathcal{P}(A)) में कितने सदस्य होंगे?

If (A) has (4) elements, how many elements will (\mathcal{P}(A)) have?

Explanation opens after your attempt
Correct Answer

C. (16)

Step 1

Concept

A power set contains all subsets, so the number is \(2^4=16\). Think separately about elements of (A) and elements of (\mathcal{P}(A)).

Step 2

Why this answer is correct

The correct answer is C. (16). A power set contains all subsets, so the number is \(2^4=16\). Think separately about elements of (A) and elements of (\mathcal{P}(A)).

Step 3

Exam Tip

घात समुच्चय में सभी उपसमुच्चय होते हैं, इसलिए संख्या \(2^4=16\) है। (A) के सदस्य और (\mathcal{P}(A)) के सदस्य अलग सोचें।
