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

संख्या 48510 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 48510?

Explanation opens after your attempt
Correct Answer

A. \(2\times3^2\times5\times7^2\times11\)

Step 1

Concept

Write \(48510=90\times539\).

Step 2

Why this answer is correct

\(90=2\times3^2\times5\) and \(539=7^2\times11\), so \(48510=2\times3^2\times5\times7^2\times11\).

Step 3

Exam Tip

Give prime form to both 90 and 539. चरण 1: \(48510=90\times539\) लिखें। चरण 2: \(90=2\times3^2\times5\) और \(539=7^2\times11\), इसलिए \(48510=2\times3^2\times5\times7^2\times11\)। चरण 3: 90 और 539 दोनों को अभाज्य रूप दें।

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

संख्या 486 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 486?

Explanation opens after your attempt
Correct Answer

A. \(2\times3^5\)

Step 1

Concept

Write \(486=2\times243\).

Step 2

Why this answer is correct

Since \(243=3^5\), \(486=2\times3^5\).

Step 3

Exam Tip

Do not leave 243 in the final answer; write it as a power of 3. चरण 1: \(486=2\times243\) लिखें। चरण 2: \(243=3^5\), इसलिए \(486=2\times3^5\)। चरण 3: 243 को अंतिम उत्तर में न छोड़कर 3 की घात में लिखें।

Question Easy Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 8

संख्या 480 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 480?

Explanation opens after your attempt
Correct Answer

A. \(2^5\times3\times5\)

Step 1

Concept

Write \(480=48\times10\).

Step 2

Why this answer is correct

\(48=2^4\times3\) and \(10=2\times5\), so \(480=2^5\times3\times5\).

Step 3

Exam Tip

Count the total power of 2 correctly. चरण 1: \(480=48\times10\) लिखें। चरण 2: \(48=2^4\times3\) और \(10=2\times5\), इसलिए \(480=2^5\times3\times5\)। चरण 3: 2 की कुल घात सही गिनें।

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

यदि किसी संख्या का अभाज्य गुणनखंडन \(2^4\times3\) है, तो वह संख्या कौन सी है?

If the prime factorisation of a number is \(2^4\times3\), which number is it?

Explanation opens after your attempt
Correct Answer

A. 48

Step 1

Concept

Calculate \(2^4=16\).

Step 2

Why this answer is correct

\(16\times3=48\).

Step 3

Exam Tip

It is easier to find the value of prime powers first. चरण 1: \(2^4=16\) निकालें। चरण 2: \(16\times3=48\)। चरण 3: अभाज्य घात का मान पहले निकालना आसान रहता है।

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

संख्या 48 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 48?

Explanation opens after your attempt
Correct Answer

A. \(2^4\times3\)

Step 1

Concept

Divide 48 repeatedly by 2.

Step 2

Why this answer is correct

We get \(48=2^4\times3\).

Step 3

Exam Tip

16 and 6 are composite, so they are not final prime answers. चरण 1: 48 को बार-बार 2 से भाग दें। चरण 2: \(48=2^4\times3\) मिलता है। चरण 3: 16 और 6 संयुक्त हैं, इसलिए अंतिम अभाज्य उत्तर नहीं हैं।
