\(3\sqrt{54}+2\sqrt{150}\) का सरल रूप क्या है?
What is the simplified form of \(3\sqrt{54}+2\sqrt{150}\)?
Correct answer and explanation
B. \(19\sqrt{6}\)
Simple Explanation
\(54=9\times6\) और \(150=25\times6\), इसलिए \(\sqrt{54}=3\sqrt{6}\) तथा \(\sqrt{150}=5\sqrt{6}\)। अतः \(3\sqrt{54}+2\sqrt{150}=3(3\sqrt{6})+2(5\sqrt{6})=9\sqrt{6}+10\sqrt{6}=19\sqrt{6}\)। इसलिए सही उत्तर B है। परीक्षा-युक्ति: समान मूल वाले करणी पदों को उनके गुणांकों की तरह जोड़ा या घटाया जा सकता है। / Since \(54=9\times6\) and \(150=25\times6\), we have \(\sqrt{54}=3\sqrt{6}\) and \(\sqrt{150}=5\sqrt{6}\). Therefore, \(3\sqrt{54}+2\sqrt{150}=3(3\sqrt{6})+2(5\sqrt{6})=9\sqrt{6}+10\sqrt{6}=19\sqrt{6}\). Hence, option B is correct. Exam tip: Radicals with the same radicand can be added or subtracted by combining their coefficients.
