Explanation opens after your attempt
Correct Answer

B. \(\sqrt{5}\)

Step 1

Concept

(4<5<9).

Step 2

Why this answer is correct

Therefore \(2<\sqrt{5}<3\) and since (5) is not a perfect square \(\sqrt{5}\) is irrational.

Step 3

Exam Tip

Use squares to locate irrational square roots between integers. चरण 1: (4<5<9) है। चरण 2: इसलिए \(2<\sqrt{5}<3\) और (5) पूर्ण वर्ग नहीं है इसलिए \(\sqrt{5}\) अपरिमेय है। चरण 3: बीच की संख्या खोजते समय वर्गों से सीमा बनाएं।
