Question 2/2 Medium Mathematics Real Numbers Prime factorisation Class 10 Level 9

संख्या 2268 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 2268?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(2268=4\times567\).

Step 2

Why this answer is correct

\(4=2^2\) and \(567=3^4\times7\), so \(2268=2^2\times3^4\times7\).

Step 3

Exam Tip

Convert 567 into complete prime form. चरण 1: \(2268=4\times567\) लिखें। चरण 2: \(4=2^2\) और \(567=3^4\times7\), इसलिए \(2268=2^2\times3^4\times7\)। चरण 3: 567 को पूरा अभाज्य रूप में बदलें।
