\(यदि (R={x\in \mathbb{N}: x\) संख्या 36 का भाजक है और x पूर्ण वर्ग है}), तो (R) कौन-सा है?
\(If (R={x\in \mathbb{N}: x\) is a divisor of 36 and x is a perfect square}), which set is (R)?
Explanation opens after your attempt
A. \(R=\{1,4,9,36\}\)
Concept
The divisors of (36) are (1,2,3,4,6,9,12,18,36).
Why this answer is correct
Among these, the perfect squares are (1,4,9,36). Hence \(R=\{1,4,9,36\}\).
Exam Tip
In a set with two properties, each element must satisfy both conditions. चरण 1: (36) के भाजक (1,2,3,4,6,9,12,18,36) हैं। चरण 2: इनमें पूर्ण वर्ग (1,4,9,36) हैं। इसलिए \(R=\{1,4,9,36\}\)। चरण 3: दो गुणों वाले समुच्चय में हर सदस्य दोनों शर्तें पूरी करे, यह जांचना जरूरी है।
