Correct Answer

A. \(\sqrt{440}\) (20) और (21) के बीच है और \(\sqrt{441}=21\) है\(\sqrt{440}\) lies between (20) and (21), and \(\sqrt{441}=21\)

Step 1

Concept

\(20^2<440<21^2\), and \(441=21^2\). Therefore \(\sqrt{441}\) is exactly at (21).

Step 2

Why this answer is correct

The correct answer is A. \(\sqrt{440}\) (20) और (21) के बीच है और \(\sqrt{441}=21\) है / \(\sqrt{440}\) lies between (20) and (21), and \(\sqrt{441}=21\). \(20^2<440<21^2\), and \(441=21^2\). Therefore \(\sqrt{441}\) is exactly at (21).

Step 3

Exam Tip

\(20^2<440<21^2\) और \(441=21^2\) है। इसलिए \(\sqrt{441}\) ठीक (21) पर है।
