Step 2

Why this answer is correct

\(32\times81\times7=18144\).

Step 3

Question 2/2 Hard Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 9

संख्या 18144 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 18144?

Explanation opens after your attempt
Correct Answer

A. \(2^5\times3^4\times7\)

Step 1

Concept

Write \(18144=32\times567\).

Step 2

Why this answer is correct

\(32=2^5\) and \(567=3^4\times7\), so \(18144=2^5\times3^4\times7\).

Step 3

Exam Tip

Give 567 its complete prime form. चरण 1: \(18144=32\times567\) लिखें। चरण 2: \(32=2^5\) और \(567=3^4\times7\), इसलिए \(18144=2^5\times3^4\times7\)। चरण 3: 567 को पूरा अभाज्य रूप दें।
