यदि \(A={x\in\mathbb{R}: 0\le x<3}\) और \(B={x\in\mathbb{R}: 1<x\le 5}\), तो \(A\cup B\) क्या है?
If \(A={x\in\mathbb{R}: 0\le x<3}\) and \(B={x\in\mathbb{R}: 1<x\le 5}\), what is \(A\cup B\)?
Explanation opens after your attempt
A. ([0,5])
Concept
The intervals overlap, so their union covers all points from (0) to (5). Both endpoints (0) and (5) are included.
Why this answer is correct
The correct answer is A. ([0,5]). The intervals overlap, so their union covers all points from (0) to (5). Both endpoints (0) and (5) are included.
Exam Tip
दोनों अंतराल ओवरलैप करते हैं, इसलिए उनका संघ (0) से (5) तक पूरा है। दोनों सिरों (0) और (5) शामिल हैं।
