यदि (A) संख्या रेखा पर (1.4) और (1.5) के बीच है और \(A=\sqrt{2}\) है, तो सबसे सही कथन कौन-सा है?
If (A) lies between (1.4) and (1.5) on the number line and \(A=\sqrt{2}\), which statement is most correct?
Explanation opens after your attempt
A. \(1.4<\sqrt{2}<1.5\)
Concept
Because \(1.4^2=1.96\) and \(1.5^2=2.25\), \(\sqrt{2}\) lies between them. For hard questions, use squares of decimals.
Why this answer is correct
The correct answer is A. \(1.4<\sqrt{2}<1.5\). Because \(1.4^2=1.96\) and \(1.5^2=2.25\), \(\sqrt{2}\) lies between them. For hard questions, use squares of decimals.
Exam Tip
क्योंकि \(1.4^2=1.96\) और \(1.5^2=2.25\), इसलिए \(\sqrt{2}\) इनके बीच है। कठिन प्रश्नों में दशमलव के वर्ग का प्रयोग करें।
