\(यदि (U={1,2,\ldots,30}), (A={x:x\in U,x\) पूर्ण वर्ग है\(}) और (B={x:x\in U,x\) सम है\(}), तो (A'\cap B) क्या है\)?
\(If (U={1,2,\ldots,30}), (A={x:x\in U,x\) is a perfect square\(}), and (B={x:x\in U,x\) is even\(}), what is (A'\cap B)\)?
Explanation opens after your attempt
Correct Answer
A. ({2,6,8,10,12,14,18,20,22,24,26,28,30})
Concept
From the even numbers in (B), the perfect squares (4) and (16) are removed. Therefore \(A'\cap B\) contains the remaining even numbers.
Why this answer is correct
The correct answer is A. ({2,6,8,10,12,14,18,20,22,24,26,28,30}). From the even numbers in (B), the perfect squares (4) and (16) are removed. Therefore \(A'\cap B\) contains the remaining even numbers.
Exam Tip
(B) की सम संख्याओं में से पूर्ण वर्ग (4) और (16) हटेंगे। इसलिए \(A'\cap B\) में बाकी सम संख्याएं आएंगी।
