Explanation opens after your attempt
Correct Answer

A. 168

Step 1

Concept

Calculate \(2^3=8\).

Step 2

Why this answer is correct

\(8\times3\times7=168\).

Step 3

Exam Tip

To get the number from prime factorisation, multiply all factors. चरण 1: \(2^3=8\) निकालें। चरण 2: \(8\times3\times7=168\)। चरण 3: अभाज्य गुणनखंडन से संख्या पाने के लिए सभी गुणनखंडों को गुणा करें।

Question 2/2 Easy Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 8

संख्या 168 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 168?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(168=8\times21\).

Step 2

Why this answer is correct

\(8=2^3\) and \(21=3\times7\), so \(168=2^3\times3\times7\).

Step 3

Exam Tip

8 and 21 are composite, so break them further. चरण 1: \(168=8\times21\) लिखें। चरण 2: \(8=2^3\) और \(21=3\times7\), इसलिए \(168=2^3\times3\times7\)। चरण 3: 8 और 21 संयुक्त हैं, इसलिए उन्हें आगे तोड़ें।
