Question 2/2 Medium Mathematics Real Numbers Prime factorisation Class 10 Level 8

संख्या 924 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 924?

Explanation opens after your attempt
Correct Answer

A. \(2^2\times3\times7\times11\)

Step 1

Concept

Write \(924=4\times231\).

Step 2

Why this answer is correct

\(4=2^2\) and \(231=3\times7\times11\), so \(924=2^2\times3\times7\times11\).

Step 3

Exam Tip

Give 231 its complete prime form. चरण 1: \(924=4\times231\) लिखें। चरण 2: \(4=2^2\) और \(231=3\times7\times11\), इसलिए \(924=2^2\times3\times7\times11\)। चरण 3: 231 को पूरा अभाज्य रूप दें।
