Which option is not correct in the proof of (\sqrt{2})?कौन सा विकल्प (\sqrt{2}) के प्रमाण में सही नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: From (a^2=2b^2), directly (a=2b)(a^2=2b^2) से सीधे (a=2b)
Step 1: From (a^2=2b^2), (a^2) is even. Step 2: This gives (a) even, but not directly (a=2b). Step 3: The correct step is to write (a=2k).चरण 1: (a^2=2b^2) से (a^2) सम मिलता है। चरण 2: इससे (a) सम है, लेकिन सीधे (a=2b) नहीं मिलता। चरण 3: सही कदम (a=2k) लिखना है।
