\(\sqrt{11}\) का लगभग मान कौन-सा है?

What is the approximate value of \(\sqrt{11}\)?

Explanation opens after your attempt
Correct Answer

B. (3.32)

Step 1

Concept

Since (9<11<16), \(\sqrt{11}\) lies between (3) and (4).

Step 2

Why this answer is correct

Its approximate value is (3.316), so (3.32) is close.

Step 3

Exam Tip

In estimation, first set the range using perfect squares. चरण 1: (9<11<16), इसलिए \(\sqrt{11}\) (3) और (4) के बीच होगा। चरण 2: इसका लगभग मान (3.316) है, इसलिए (3.32) निकट है। चरण 3: अनुमान में पहले पूर्ण वर्गों से सीमा तय करें।

Step 2

Why this answer is correct

\(\sqrt{112}=\sqrt{16 \times 7}=4\sqrt{7}\).

Step 3
