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

संख्या 27720 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 27720?

Explanation opens after your attempt
Correct Answer

A. \(2^3\times3^2\times5\times7\times11\)

Step 1

Concept

Write \(27720=8\times3465\).

Step 2

Why this answer is correct

\(3465=3^2\times5\times7\times11\), so \(27720=2^3\times3^2\times5\times7\times11\).

Step 3

Exam Tip

Give 3465 its complete prime form. चरण 1: \(27720=8\times3465\) लिखें। चरण 2: \(3465=3^2\times5\times7\times11\), इसलिए \(27720=2^3\times3^2\times5\times7\times11\)। चरण 3: 3465 को पूरा अभाज्य रूप दें।

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

यदि \(27720=2^a\times3^2\times5\times7\times11\), तो (a) का मान क्या है?

If \(27720=2^a\times3^2\times5\times7\times11\), what is the value of (a)?

Explanation opens after your attempt
Correct Answer

A. 3

Step 1

Concept

\(27720=8\times3465\).

Step 2

Why this answer is correct

\(8=2^3\) and \(3465=3^2\times5\times7\times11\), so the power of 2 is 3.

Step 3

Exam Tip

Comparing gives (a=3). चरण 1: \(27720=8\times3465\) है। चरण 2: \(8=2^3\) और \(3465=3^2\times5\times7\times11\), इसलिए 2 की घात 3 है। चरण 3: तुलना करने पर (a=3) है।

What is the correct prime factorisation of 2772?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(2772=36\times77\).

Step 2

Why this answer is correct

\(36=2^2\times3^2\) and \(77=7\times11\), so \(2772=2^2\times3^2\times7\times11\).

Step 3

Exam Tip

Write 36 and 77 in prime form. चरण 1: \(2772=36\times77\) लिखें। चरण 2: \(36=2^2\times3^2\) और \(77=7\times11\), इसलिए \(2772=2^2\times3^2\times7\times11\)। चरण 3: 36 और 77 को अभाज्य रूप में लिखें।
