Question Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 9

संख्या 2640 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 2640?

Explanation opens after your attempt
Correct Answer

A. \(2^4\times3\times5\times11\)

Step 1

Concept

Write \(2640=16\times165\).

Step 2

Why this answer is correct

\(16=2^4\) and \(165=3\times5\times11\), so \(2640=2^4\times3\times5\times11\).

Step 3

Exam Tip

Break 165 further. चरण 1: \(2640=16\times165\) लिखें। चरण 2: \(16=2^4\) और \(165=3\times5\times11\), इसलिए \(2640=2^4\times3\times5\times11\)। चरण 3: 165 को आगे तोड़ें।
