Hard Mathematics Chapter 1: Real Numbers Class 10 Level 13

यदि (48), (75) और (125) का लघुत्तम समापवर्त्य निकाला जाए, तो उसमें (5) की घात क्या होगी?

If the LCM of (48), (75), and (125) is found, what will be the power of (5) in it?

Explanation opens after your attempt
Correct Answer

C. (3)

Step 1

Concept

Look at the powers of (5). (48) has no factor (5), \(75=3\times5^2\), and \(125=5^3\).

Step 2

Why this answer is correct

The highest power of (5) in the LCM is (3).

Step 3

Exam Tip

A missing prime has power zero, but still compare the existing highest power. चरण 1: (5) की घातों को देखें। (48) में (5) नहीं है, \(75=3\times5^2\) और \(125=5^3\) है। चरण 2: लघुत्तम समापवर्त्य में (5) की सबसे बड़ी घात (3) होगी। चरण 3: जिस अभाज्य की घात शून्य हो, उसे तुलना में भूलें नहीं।
