Correct Answer

B. (99)

Step 1

The square root of a perfect square is rational.

Step 2

Why this answer is correct

(99) is not a perfect square, so \(\sqrt{99}\) is irrational.

Step 3

Exam Tip

In such questions, first separate the perfect squares. चरण 1: पूर्ण वर्ग का वर्गमूल परिमेय होता है। चरण 2: (99) पूर्ण वर्ग नहीं है, इसलिए \(\sqrt{99}\) अपरिमेय होगा। चरण 3: ऐसे प्रश्नों में पहले पूर्ण वर्गों को अलग कर दें।
