Question
Medium Mathematics
Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 8
यदि \(2100=2^2\times3\times5^q\times7\), तो (q) का मान क्या है?
If \(2100=2^2\times3\times5^q\times7\), what is the value of (q)?

A 2
B 1
C 3
D 4
Explanation opens after your attempt
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।

संख्या 2100 का अभाज्य गुणनखंडन कौन सा है?
Which is the prime factorisation of 2100?
#prime-factorisation
#number-2100
#medium
A \(2^2\times3\times5^2\times7\)
B \(2\times3\times5^2\times7\)
C \(21\times100\)
D \(2^2\times3\times25\times7\)
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।
