\(यदि (A={x\in \mathbb{N}:x\) is a divisor of \(36}) और (B={1,2,3,4,6,9,12,18,36}) है, तो (n(A)) और (A=B) के बारे में सही विकल्प कौन सा है\)?
\(If (A={x\in \mathbb{N}:x\) is a divisor of \(36}) and (B={1,2,3,4,6,9,12,18,36}), which option is correct about (n(A)) and (A=B)\)?
Correct answer and explanation
A. (n(A)=9) और (A=B)(n(A)=9) and (A=B)
Concept
(36) के धनात्मक भाजक (1,2,3,4,6,9,12,18,36) हैं। / The positive divisors of (36) are (1,2,3,4,6,9,12,18,36).
Why this answer is correct
कुल (9) अवयव हैं और यही (B) में हैं। / There are (9) elements, exactly the same as (B).
Exam Tip
भाजक गिनते समय जोड़ी विधि से कोई अवयव न छूटे। / Use factor pairs so that no divisor is missed.
