अंकगणित के मूल प्रमेय में अभाज्य गुणनखंडन की अद्वितीयता का सही अर्थ क्या है?

What is the correct meaning of uniqueness in the Fundamental Theorem of Arithmetic?

Explanation opens after your attempt
Correct Answer

A. गुणनखंडों का क्रम बदल सकता है पर अभाज्य गुणनखंड वही रहते हैंThe order of factors may change but the prime factors remain the same

Step 1

Concept

The theorem says that prime factorisation of a number greater than 1 is fixed.

Step 2

Why this answer is correct

Changing the order does not change the product, such as \(2\times3\times5\) and \(5\times2\times3\).

Step 3

Exam Tip

In exams, do not treat changed order as a different factorisation. चरण 1: यह प्रमेय बताता है कि 1 से बड़ी संख्या का अभाज्य गुणनखंडन निश्चित होता है। चरण 2: क्रम बदलने से गुणनफल नहीं बदलता, जैसे \(2\times3\times5\) और \(5\times2\times3\)। चरण 3: परीक्षा में क्रम देखकर अलग गुणनखंडन न मानें।
