Correct Answer

A. \(2^3\times3^3\times5\times7^2\)

Step 1

Concept

In the final form, every base must be prime.

Step 2

Why this answer is correct

In the first option, bases 2, 3, 5, and 7 are prime.

Step 3

Exam Tip

8, 135, 49, 27, 245, and 216 are composite, so they are not final forms. चरण 1: अंतिम रूप में हर आधार अभाज्य होना चाहिए। चरण 2: पहले विकल्प में आधार 2, 3, 5 और 7 अभाज्य हैं। चरण 3: 8, 135, 49, 27, 245 और 216 संयुक्त हैं, इसलिए वे अंतिम रूप नहीं हैं।
