If (a=\sqrt{13}-\sqrt{52}), what is the simplified form of (a)?यदि (a=\sqrt{13}-\sqrt{52}), तो (a) का सरल रूप क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-\sqrt{13})(-\sqrt{13})
Step 1: (\sqrt{52}=2\sqrt{13}). Step 2: (a=\sqrt{13}-2\sqrt{13}=-\sqrt{13}), which is irrational. Step 3: A negative sign does not change irrationality.चरण 1: (\sqrt{52}=2\sqrt{13}) है। चरण 2: (a=\sqrt{13}-2\sqrt{13}=-\sqrt{13}), जो अपरिमेय है। चरण 3: ऋण चिह्न आने पर भी अपरिमेयता नहीं बदलती।
