\(यदि (U={1,2,3,\ldots,36}) और (A={x:x\) पूर्ण वर्ग है\(}) है, तो (n(A^c)) कितना होगा\)?
\(If (U={1,2,3,\ldots,36}) and (A={x:x\) is a perfect square\(}), what is (n(A^c))\)?
Explanation opens after your attempt
Correct Answer
A. (30)
Concept
The perfect squares from (1) to (36) are (1,4,9,16,25,36). Hence (n\(A^c\)=36-6=30).
Why this answer is correct
The correct answer is A. (30). The perfect squares from (1) to (36) are (1,4,9,16,25,36). Hence (n\(A^c\)=36-6=30).
Exam Tip
(1) से (36) तक पूर्ण वर्ग (1,4,9,16,25,36) हैं। इसलिए (n\(A^c\)=36-6=30) होगा।
