Question Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 7

यदि \(2^2\times5^4\) किसी संख्या का अभाज्य गुणनखंडन है, तो संख्या क्या है?

If \(2^2\times5^4\) is the prime factorisation of a number, what is the number?

Explanation opens after your attempt
Correct Answer

A. 2500

Step 1

Concept

Calculate \(2^2=4\) and \(5^4=625\).

Step 2

Why this answer is correct

\(4\times625=2500\).

Step 3

Exam Tip

Finding the higher power first makes the answer easier. चरण 1: \(2^2=4\) और \(5^4=625\) निकालें। चरण 2: \(4\times625=2500\)। चरण 3: बड़ी घात को पहले निकालने से उत्तर आसान बनता है।

Question Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 7

संख्या 2500 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 2500?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(2500=25\times100\).

Step 2

Why this answer is correct

\(25=5^2\) and \(100=2^2\times5^2\), so \(2500=2^2\times5^4\).

Step 3

Exam Tip

Count the total power of 5 as 4. चरण 1: \(2500=25\times100\) लिखें। चरण 2: \(25=5^2\) और \(100=2^2\times5^2\), इसलिए \(2500=2^2\times5^4\)। चरण 3: 5 की कुल घात 4 गिनें।

संख्या 2500 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 2500?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(2500=25\times100\).

Step 2
