Explanation opens after your attempt
Correct Answer

A. 2

Step 1

Concept

\(2100=21\times100\).

Step 2

Why this answer is correct

\(21=3\times7\) and \(100=2^2\times5^2\), so the power of 5 is 2.

Step 3

Exam Tip

Therefore, (q=2). चरण 1: \(2100=21\times100\) है। चरण 2: \(21=3\times7\) और \(100=2^2\times5^2\), इसलिए 5 की घात 2 है। चरण 3: इसलिए (q=2) होगा।

Which is the prime factorisation of 2100?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(2100=21\times100\).

Step 2

Why this answer is correct

\(21=3\times7\) and \(100=2^2\times5^2\), so \(2100=2^2\times3\times5^2\times7\).

Step 3

Exam Tip

Do not keep 25 or 100 in the final answer. चरण 1: \(2100=21\times100\) लिखें। चरण 2: \(21=3\times7\) और \(100=2^2\times5^2\), इसलिए \(2100=2^2\times3\times5^2\times7\)। चरण 3: 25 या 100 को अंतिम उत्तर में न रखें।
