Correct Answer

B. \(\sqrt{440}\) (20) और (21) के बीच है, \(\sqrt{442}\) (21) और (22) के बीच है\(\sqrt{440}\) lies between (20) and (21), \(\sqrt{442}\) lies between (21) and (22)

Step 1

Concept

Since \(440<441=21^2\), \(\sqrt{440}<21\). Since (442>441), \(\sqrt{442}>21\).

Step 2

Why this answer is correct

The correct answer is B. \(\sqrt{440}\) (20) और (21) के बीच है, \(\sqrt{442}\) (21) और (22) के बीच है / \(\sqrt{440}\) lies between (20) and (21), \(\sqrt{442}\) lies between (21) and (22). Since \(440<441=21^2\), \(\sqrt{440}<21\). Since (442>441), \(\sqrt{442}>21\).

Step 3

Exam Tip

\(440<441=21^2\), इसलिए \(\sqrt{440}<21\)। (442>441), इसलिए \(\sqrt{442}>21\)।
