Which option gives the correct interval of (-1+\sqrt{5}) on the number line?किस विकल्प में संख्या रेखा पर (-1+\sqrt{5}) का सही अंतराल है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((1,2))((1,2))
Since (2<\sqrt{5}<3), (1<-1+\sqrt{5}<2). When adding or subtracting a constant, adjust the whole inequality.क्योंकि (2<\sqrt{5}<3), इसलिए (1<-1+\sqrt{5}<2)। स्थिर संख्या जोड़ने या घटाने पर पूरी असमानता बदलें।
