यदि \(x=\sqrt{529}\div\sqrt{23}\) तो (x) क्या है?
If \(x=\sqrt{529}\div\sqrt{23}\), what is (x)?
Correct answer and explanation
A. \(\sqrt{23}\)
Simple Explanation
क्योंकि \(529=23^2\), इसलिए \(\sqrt{529}=23\)। अतः \(x=\frac{23}{\sqrt{23}}=\frac{\sqrt{23}\times\sqrt{23}}{\sqrt{23}}=\sqrt{23}\)। विकल्प 23 इसलिए गलत है क्योंकि हर में \(\sqrt{23}\) से भाग देना शेष रहता है। परीक्षा टिप: \(a=\sqrt{a}\times\sqrt{a}\) का उपयोग करके ऐसे वर्गमूल वाले भिन्न को सरल करें। / Since \(529=23^2\), we get \(\sqrt{529}=23\). Therefore, \(x=\frac{23}{\sqrt{23}}=\frac{\sqrt{23}\times\sqrt{23}}{\sqrt{23}}=\sqrt{23}\). Option 23 is incorrect because division by \(\sqrt{23}\) still remains. Exam tip: Use \(a=\sqrt{a}\times\sqrt{a}\) to simplify fractions involving square roots.
