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

संख्या 210 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 210?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write \(210=21\times10\).

Step 2

Why this answer is correct

\(21=3\times7\) and \(10=2\times5\), so \(210=2\times3\times5\times7\).

Step 3

Exam Tip

Do not keep 21 or 10 in the final answer. चरण 1: \(210=21\times10\) लिखें। चरण 2: \(21=3\times7\) और \(10=2\times5\), इसलिए \(210=2\times3\times5\times7\)। चरण 3: अंतिम उत्तर में 21 या 10 न रखें।
