If (t=\sqrt{13}+\sqrt{12}), what is the value of (t\cdot(\sqrt{13}-\sqrt{12}))?यदि (t=\sqrt{13}+\sqrt{12}), तो (t\cdot(\sqrt{13}-\sqrt{12})) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1)(1)
((\sqrt{13}+\sqrt{12})(\sqrt{13}-\sqrt{12})=13-12=1). In exams, the product of conjugate surds is rational.((\sqrt{13}+\sqrt{12})(\sqrt{13}-\sqrt{12})=13-12=1)। परीक्षा में करणी वाले संयुग्म का गुणनफल परिमेय होता है।
