Correct Answer

A. \(\sqrt{255}\) (15) और (16) के बीच है, \(\sqrt{257}\) (16) और (17) के बीच है\(\sqrt{255}\) lies between (15) and (16), \(\sqrt{257}\) lies between (16) and (17)

Step 1

Concept

Since \(255<256=16^2\), \(\sqrt{255}<16\). Since (257>256), \(\sqrt{257}>16\).

Step 2

Why this answer is correct

The correct answer is A. \(\sqrt{255}\) (15) और (16) के बीच है, \(\sqrt{257}\) (16) और (17) के बीच है / \(\sqrt{255}\) lies between (15) and (16), \(\sqrt{257}\) lies between (16) and (17). Since \(255<256=16^2\), \(\sqrt{255}<16\). Since (257>256), \(\sqrt{257}>16\).

Step 3

Exam Tip

\(255<256=16^2\), इसलिए \(\sqrt{255}<16\)। (257>256), इसलिए \(\sqrt{257}>16\)।
