Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (5.4<\sqrt{30}<5.5)(5.4<\sqrt{30}<5.5)
(5.4^2=29.16) and (5.5^2=30.25), so ( \sqrt{30} ) lies between them. Check squares for decimal bounds.(5.4^2=29.16) और (5.5^2=30.25), इसलिए ( \sqrt{30} ) इनके बीच है। दशमलव सीमा के लिए वर्ग जाँचें।
