Explanation opens after your attempt
Correct Answer

A. \(\sqrt{5}\)

Step 1

Concept

Since (4<5<9), \(2<\sqrt{5}<3\).

Step 2

Why this answer is correct

(5) is not a perfect square, so \(\sqrt{5}\) is irrational.

Step 3

Exam Tip

Use nearby perfect squares to locate a square root. चरण 1: (4<5<9), इसलिए \(2<\sqrt{5}<3\)। चरण 2: (5) पूर्ण वर्ग नहीं है, इसलिए \(\sqrt{5}\) अपरिमेय है। चरण 3: वर्गमूल की स्थिति जानने के लिए पास के पूर्ण वर्ग देखें।
