\(कौन-सा विकल्प (T={x:x\) एक प्राकृतिक संख्या है और \(3\leq x\leq 7}) का सूची रूप है\)?
\(Which option is the roster form of (T={x:x\) is a natural number and \(3\leq x\leq 7})\)?
Explanation opens after your attempt
A. \(T=\{3,4,5,6,7\}\)
Concept
\(3\leq x\leq 7\) means both (3) and (7) are included.
Why this answer is correct
The natural numbers in this range are (3,4,5,6,7).
Exam Tip
Do not leave out endpoints when \(\leq\) is used. चरण 1: \(3\leq x\leq 7\) का अर्थ है (3) और (7) दोनों शामिल हैं। चरण 2: इनके बीच की प्राकृतिक संख्याएँ (3,4,5,6,7) हैं। चरण 3: \(\leq\) वाले सिरों को छोड़ना नहीं चाहिए।
