\(यदि (U={1,2,3,\ldots,16}) और (A={x:x \in U,\ x\) पूर्ण वर्ग है\(}), तो (A^{c}) में कितने अवयव हैं\)?

\(If (U={1,2,3,\ldots,16}) and (A={x:x \in U,\ x\) is a perfect square\(}), how many elements are in (A^{c})\)?

Explanation opens after your attempt
Correct Answer

C. (12)

Step 1

Concept

\(A=\{1,4,9,16\}\), so (n\(A^{c}\)=16-4=12). List the perfect squares first.

Step 2

Why this answer is correct

The correct answer is C. (12). \(A=\{1,4,9,16\}\), so (n\(A^{c}\)=16-4=12). List the perfect squares first.

Step 3

Exam Tip

\(A=\{1,4,9,16\}\) है, इसलिए (n\(A^{c}\)=16-4=12)। पूर्ण वर्गों की सूची पहले बना लें।
