\(यदि (M_1={x:x\in \mathbb{N},,x\) is a divisor of 100 and x is a square number\(}), तो (M_1) क्या है\)?
\(If (M_1={x:x\in \mathbb{N},,x\) is a divisor of 100 and x is a square number\(}), what is (M_1)\)?
Explanation opens after your attempt
A. \(M_1={1,4,25,100}\)
Concept
Divisors of (100) are (1,2,4,5,10,20,25,50,100).
Why this answer is correct
The square numbers among them are (1,4,25,100).
Exam Tip
Being a square is not enough; it must also divide (100). चरण 1: (100) के भाजक (1,2,4,5,10,20,25,50,100) हैं। चरण 2: इनमें पूर्ण वर्ग (1,4,25,100) हैं। चरण 3: केवल वर्ग संख्या होना काफी नहीं, वह (100) का भाजक भी होनी चाहिए।
