Correct Answer

A. क्योंकि सभी घातें सम नहीं हैंBecause all exponents are not even

Step 1

Concept

The square root of a number is an integer only when all prime exponents are even.

Step 2

Why this answer is correct

In \(2^5 \times 3\), the exponents are (5) and (1), both odd.

Step 3

Exam Tip

For square-root questions, check evenness of exponents first. चरण 1: किसी संख्या का वर्गमूल पूर्ण संख्या तभी होता है जब सभी अभाज्य घातें सम हों। चरण 2: \(2^5 \times 3\) में घात (5) और (1) हैं, दोनों विषम हैं। चरण 3: वर्गमूल से जुड़े प्रश्नों में घातों की समता सबसे पहले देखें।
