\(यदि (A={x\in \mathbb{N}:x\) is a square number less than \(50}) और (B={1,4,9,16,25,36,49}) है, तो कौन सा कथन सही है\)?
\(If (A={x\in \mathbb{N}:x\) is a square number less than \(50}) and (B={1,4,9,16,25,36,49}), which statement is correct\)?
Explanation opens after your attempt
A. (A=B)
Concept
Square numbers less than (50) are from \(1^2\) to \(7^2\).
Why this answer is correct
\(8^2=64\) is outside the limit.
Exam Tip
Apply both the square-number condition and the bound together. चरण 1: (50) से छोटी वर्ग संख्याएँ \(1^2\) से \(7^2\) तक मिलती हैं। चरण 2: \(8^2=64\) सीमा से बाहर है। चरण 3: सीमा और वर्ग दोनों शर्तों को साथ रखें।
