यदि \(A={x\in\mathbb{N}: x\mid 18}\) और \(B={x\in\mathbb{N}: x\mid 24}\), तो \(A\cup B\) क्या है?
If \(A={x\in\mathbb{N}: x\mid 18}\) and \(B={x\in\mathbb{N}: x\mid 24}\), what is \(A\cup B\)?
Explanation opens after your attempt
Correct Answer
A. ({1,2,3,4,6,8,9,12,18,24})
Concept
Divisors of (18) are ({1,2,3,6,9,18}), and divisors of (24) are ({1,2,3,4,6,8,12,24}). Combining without repetition gives the union.
Why this answer is correct
The correct answer is A. ({1,2,3,4,6,8,9,12,18,24}). Divisors of (18) are ({1,2,3,6,9,18}), and divisors of (24) are ({1,2,3,4,6,8,12,24}). Combining without repetition gives the union.
Exam Tip
(18) के भाजक ({1,2,3,6,9,18}) और (24) के भाजक ({1,2,3,4,6,8,12,24}) हैं। दोनों को बिना दोहराव मिलाने पर सही संघ मिलता है।
