अभाज्य गुणनखंडन में \(12^2\) को अंतिम रूप क्यों नहीं माना जाता?

Why is \(12^2\) not considered a final form in prime factorisation?

Explanation opens after your attempt
Correct Answer

A. क्योंकि 12 संयुक्त संख्या हैBecause 12 is composite

Step 1

Concept

In final prime factorisation, the base must be prime.

Step 2

Why this answer is correct

12 is composite and \(12=2^2\times3\).

Step 3

Exam Tip

Therefore, \(12^2\) must be changed further into \(2^4\times3^2\). चरण 1: अंतिम अभाज्य गुणनखंडन में आधार अभाज्य होना चाहिए। चरण 2: 12 संयुक्त है और \(12=2^2\times3\) है। चरण 3: इसलिए \(12^2\) को आगे \(2^4\times3^2\) में बदलना होगा।
