यदि (a) संख्या रेखा पर \( \sqrt{50} \) है, तो (a-7) किसके सबसे निकट है?
If (a) is \( \sqrt{50} \) on the number line, then (a-7) is closest to which value?
Explanation opens after your attempt
A. (0.07)
Concept
\( \sqrt{50}\approx7.071\), so \(a-7\approx0.071\). First estimate the root, then subtract.
Why this answer is correct
The correct answer is A. (0.07). \( \sqrt{50}\approx7.071\), so \(a-7\approx0.071\). First estimate the root, then subtract.
Exam Tip
\( \sqrt{50}\approx7.071\), इसलिए \(a-7\approx0.071\)। पहले मूल का अनुमान लगाएँ, फिर घटाएँ।
