Hard Mathematics Chapter 1: Real Numbers Class 10 Level 13

यदि \(2^4\times3\times5^2\) और \(2^2\times3^3\times5\) का लघुत्तम समापवर्त्य (L) है, तो (L) में (3) की घात क्या होगी?

If (L) is the LCM of \(2^4\times3\times5^2\) and \(2^2\times3^3\times5\), what will be the power of (3) in (L)?

Correct Answer

C. (3)

Step 1

Concept

LCM uses the higher power of every prime.

Step 2

Why this answer is correct

The powers of (3) are (1) and (3), so (L) contains \(3^3\).

Step 3

Exam Tip

Compare powers only for the same base. चरण 1: लघुत्तम समापवर्त्य में हर अभाज्य की बड़ी घात आती है। चरण 2: (3) की घातें (1) और (3) हैं, इसलिए (L) में \(3^3\) होगा। चरण 3: घातों की तुलना समान आधार पर ही करें।
