Which option is not a final prime factorisation?

Explanation opens after your attempt
Correct Answer

A. \(6\times5^2\)

Step 1

Concept

Final prime factorisation must not contain a composite factor.

Step 2

Why this answer is correct

6 is composite, so \(6\times5^2\) is not final form.

Step 3

Exam Tip

Change 6 into \(2\times3\). चरण 1: अंतिम अभाज्य गुणनखंडन में संयुक्त गुणनखंड नहीं होना चाहिए। चरण 2: 6 संयुक्त संख्या है, इसलिए \(6\times5^2\) अंतिम रूप नहीं है। चरण 3: 6 को \(2\times3\) में बदलें।
