Which number has prime factorisation \(2^4\times3\times5\times13\)?

Explanation opens after your attempt
Correct Answer

A. 3120

Step 1

Concept

Calculate \(2^4=16\).

Step 2

Why this answer is correct

\(16\times3\times5\times13=3120\).

Step 3

Exam Tip

It is easy to first treat \(3\times5\times13\) as 195 and multiply. चरण 1: \(2^4=16\) निकालें। चरण 2: \(16\times3\times5\times13=3120\)। चरण 3: पहले \(3\times5\times13\) को 195 समझकर गुणा करना आसान है।

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

संख्या 3120 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 3120?

Explanation opens after your attempt
Correct Answer

A. \(2^4\times3\times5\times13\)

Step 1

Concept

Write \(3120=16\times195\).

Step 2

Why this answer is correct

\(16=2^4\) and \(195=3\times5\times13\), so \(3120=2^4\times3\times5\times13\).

Step 3

Exam Tip

Give 195 its complete prime form. चरण 1: \(3120=16\times195\) लिखें। चरण 2: \(16=2^4\) और \(195=3\times5\times13\), इसलिए \(3120=2^4\times3\times5\times13\)। चरण 3: 195 को पूरा अभाज्य रूप दें।
