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

संख्या 7560 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 7560?

Explanation opens after your attempt
Correct Answer

A. \(2^3\times3^3\times5\times7\)

Step 1

Concept

Write \(7560=8\times945\).

Step 2

Why this answer is correct

\(8=2^3\) and \(945=3^3\times5\times7\), so \(7560=2^3\times3^3\times5\times7\).

Step 3

Exam Tip

Do not leave 945 in the final form. चरण 1: \(7560=8\times945\) लिखें। चरण 2: \(8=2^3\) और \(945=3^3\times5\times7\), इसलिए \(7560=2^3\times3^3\times5\times7\)। चरण 3: 945 को अंतिम रूप में न छोड़ें।

संख्या 7560 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 7560?

Explanation opens after your attempt
Correct Answer

A. \(2^3\times3^3\times5\times7\)

Step 1

Concept

Write \(7560=756\times10\).

Step 2

Why this answer is correct

\(756=2^2\times3^3\times7\) and \(10=2\times5\), so \(7560=2^3\times3^3\times5\times7\).

Step 3

Exam Tip

Count the total power of 2 as 3. चरण 1: \(7560=756\times10\) लिखें। चरण 2: \(756=2^2\times3^3\times7\) और \(10=2\times5\), इसलिए \(7560=2^3\times3^3\times5\times7\)। चरण 3: 2 की कुल घात 3 गिनें।

संख्या 756 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 756?

Explanation opens after your attempt
Correct Answer

A. \(2^2\times3^3\times7\)

Step 1

Concept

Write \(756=27\times28\).

Step 2

Why this answer is correct

\(27=3^3\) and \(28=2^2\times7\), so \(756=2^2\times3^3\times7\).

Step 3

Exam Tip

Give complete prime form to both parts. चरण 1: \(756=27\times28\) लिखें। चरण 2: \(27=3^3\) और \(28=2^2\times7\), इसलिए \(756=2^2\times3^3\times7\)। चरण 3: दोनों भागों को पूरा अभाज्य रूप दें।

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

संख्या 75 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 75?

Explanation opens after your attempt
Correct Answer

A. \(3\times5^2\)

Step 1

Concept

Write \(75=3\times25\).

Step 2

Why this answer is correct

Since \(25=5^2\), \(75=3\times5^2\).

Step 3

Exam Tip

25 is composite, so write \(5^2\) in the final form. चरण 1: \(75=3\times25\) लिखें। चरण 2: \(25=5^2\), इसलिए \(75=3\times5^2\)। चरण 3: 25 संयुक्त है, इसलिए अंतिम रूप में \(5^2\) लिखें।
