Correct Answer

A. 5040

Step 1

Concept

Calculate \(2^4=16\) and \(3^2=9\).

Question 2/2 Hard Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 7

संख्या 5040 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 5040?

Explanation opens after your attempt
Correct Answer

A. \(2^4\times3^2\times5\times7\)

Step 1

Concept

Write \(5040=16\times315\).

Step 2

Why this answer is correct

\(16=2^4\) and \(315=3^2\times5\times7\), so \(5040=2^4\times3^2\times5\times7\).

Step 3

Exam Tip

Give 315 its complete prime form. चरण 1: \(5040=16\times315\) लिखें। चरण 2: \(16=2^4\) और \(315=3^2\times5\times7\), इसलिए \(5040=2^4\times3^2\times5\times7\)। चरण 3: 315 को पूरा अभाज्य रूप दें।
