Which option gives the correct expansion of \(\left(\sqrt{11}-\sqrt{2}\right)^{2}\)?किस विकल्प में \(\left(\sqrt{11}-\sqrt{2}\right)^{2}\) का सही विस्तार है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(13-2\sqrt{22}\)\(13-2\sqrt{22}\)
\((\sqrt{11}-\sqrt{2})^{2}=11+2-2\sqrt{22}=13-2\sqrt{22}\). In exams, include both \(+b^{2}\) and (-2ab) in \((a-b)^{2}\).\((\sqrt{11}-\sqrt{2})^{2}=11+2-2\sqrt{22}=13-2\sqrt{22}\)। परीक्षा में \((a-b)^{2}\) में \(+b^{2}\) और (-2ab) दोनों लिखें।
