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

संख्या 13230 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 13230?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(13230=270\times49\).

Step 2

Why this answer is correct

\(270=2\times3^3\times5\) and \(49=7^2\), so \(13230=2\times3^3\times5\times7^2\).

Step 3

Exam Tip

Do not keep 270 and 49 in the final form. चरण 1: \(13230=270\times49\) लिखें। चरण 2: \(270=2\times3^3\times5\) और \(49=7^2\), इसलिए \(13230=2\times3^3\times5\times7^2\)। चरण 3: 270 और 49 को अंतिम रूप में न रखें।

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

संख्या 1323 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 1323?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(1323=27\times49\).

Step 2

Why this answer is correct

\(27=3^3\) and \(49=7^2\), so \(1323=3^3\times7^2\).

Step 3

Exam Tip

Both 27 and 49 are composite, so write them as prime powers. चरण 1: \(1323=27\times49\) लिखें। चरण 2: \(27=3^3\) और \(49=7^2\), इसलिए \(1323=3^3\times7^2\)। चरण 3: 27 और 49 दोनों संयुक्त हैं, इसलिए अभाज्य घातों में लिखें।

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

यदि किसी संख्या का अभाज्य गुणनखंडन \(2^2\times3\times11\) है, तो वह संख्या कौन सी है?

If the prime factorisation of a number is \(2^2\times3\times11\), which number is it?

Explanation opens after your attempt
Correct Answer

A. 132

Step 1

Concept

Calculate \(2^2=4\).

Step 2

Why this answer is correct

\(4\times3\times11=132\).

Step 3

Exam Tip

Multiply all factors to get the number from prime factorisation. चरण 1: \(2^2=4\) निकालें। चरण 2: \(4\times3\times11=132\)। चरण 3: अभाज्य गुणनखंडन से संख्या पाने के लिए सभी गुणनखंडों का गुणा करें।

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

संख्या 132 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 132?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(132=4\times33\).

Step 2

Why this answer is correct

\(4=2^2\) and \(33=3\times11\), so \(132=2^2\times3\times11\).

Step 3

Exam Tip

Do not keep composite factors like 4 and 33 in the final answer. चरण 1: \(132=4\times33\) लिखें। चरण 2: \(4=2^2\) और \(33=3\times11\), इसलिए \(132=2^2\times3\times11\)। चरण 3: अंतिम उत्तर में 4 और 33 जैसे संयुक्त गुणनखंड न रखें।
