Which option correctly writes (\frac{2}{\sqrt{5}+1}) with a rational denominator?कौन सा विकल्प (\frac{2}{\sqrt{5}+1}) को परिमेय हर वाले रूप में सही लिखता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{\sqrt{5}-1}{2})(\frac{\sqrt{5}-1}{2})
Step 1: Multiply by the conjugate (\sqrt{5}-1). Step 2: (\frac{2(\sqrt{5}-1)}{5-1}=\frac{\sqrt{5}-1}{2}). Step 3: Multiplying by the conjugate makes the denominator rational.चरण 1: हर को (\sqrt{5}-1) से गुणा करें। चरण 2: (\frac{2(\sqrt{5}-1)}{5-1}=\frac{\sqrt{5}-1}{2})। चरण 3: संयुग्मी से गुणा करने पर हर परिमेय बन जाता है।
