यदि \(H_1={x:x\in \mathbb{R}, x^2=2}\) और \(I_1={-\sqrt{2},\sqrt{2}}\) हैं, तो सही कथन कौन-सा है?
If \(H_1={x:x\in \mathbb{R}, x^2=2}\) and \(I_1={-\sqrt{2},\sqrt{2}}\), which statement is correct?
Explanation opens after your attempt
A. \(H_1=I_1\)
Concept
वास्तविक संख्याओं में \(x^2=2\) के दो हल \(-\sqrt{2}\) और \(\sqrt{2}\) हैं। / In real numbers, \(x^2=2\) has two solutions, \(-\sqrt{2}\) and \(\sqrt{2}\).
Why this answer is correct
यही दोनों अवयव \(I_1\) में हैं। / These are exactly the elements of \(I_1\).
Exam Tip
मूल चिह्न वाले अवयव भी समुच्चय के वैध अवयव हो सकते हैं। / Elements involving radicals can also be valid set elements.
