Which option is a correct middle step in the proof of (\sqrt{5})?कौन सा विकल्प (\sqrt{5}) के प्रमाण में सही मध्य चरण है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: From (a^2=5b^2), (a) is divisible by (5)(a^2=5b^2) से (a) (5) से विभाज्य है
Step 1: From (a^2=5b^2), (a^2) is divisible by (5). Step 2: Since (5) is prime, (a) is also divisible by (5). Step 3: This is the correct middle step, not directly (a=5b).चरण 1: (a^2=5b^2) से (a^2) (5) से विभाज्य है। चरण 2: (5) अभाज्य है, इसलिए (a) भी (5) से विभाज्य है। चरण 3: यही सही मध्य चरण है, सीधे (a=5b) नहीं।
