Question 2/2 Easy Mathematics Real Numbers Prime factorisation Class 10 Level 7

संख्या 50 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 50?

Explanation opens after your attempt
Correct Answer

A. \(2\times5^2\)

Step 1

Concept

Write \(50=2\times25\).

Step 2

Why this answer is correct

Since \(25=5^2\), \(50=2\times5^2\).

Step 3

Exam Tip

25 is composite, so write \(5^2\) in the final form. चरण 1: \(50=2\times25\) लिखें। चरण 2: \(25=5^2\), इसलिए \(50=2\times5^2\)। चरण 3: 25 संयुक्त है, इसलिए अंतिम रूप में \(5^2\) लिखें।
