If (A=7+4\sqrt{3}), what is the correct simplified form of (\sqrt{A})?यदि (A=7+4\sqrt{3}), तो (\sqrt{A}) का सही सरल रूप क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2+\sqrt{3})(2+\sqrt{3})
Since ((2+\sqrt{3})^{2}=4+3+4\sqrt{3}=7+4\sqrt{3}), (\sqrt{A}=2+\sqrt{3}). In exams, recognize the form ((a+b)^{2}).((2+\sqrt{3})^{2}=4+3+4\sqrt{3}=7+4\sqrt{3}), इसलिए (\sqrt{A}=2+\sqrt{3})। परीक्षा में रूप ((a+b)^{2}) पहचानें।
