Hard Mathematics Chapter 1: Real Numbers Class 10 Level 13

यदि \(a=2^4\times3^2\times13\) और \(b=2^2\times3^5\times5\times13\), तो \(\frac{\text{लघुत्तम समापवर्त्य}}{\text{महत्तम समापवर्तक}}\) क्या होगा?

If \(a=2^4\times3^2\times13\) and \(b=2^2\times3^5\times5\times13\), what is \(\frac{\text{LCM}}{\text{HCF}}\)?

Explanation opens after your attempt
Correct Answer

A. \(2^2\times3^3\times5\)

Step 1

Concept

HCF is \(2^2\times3^2\times13\), and LCM is \(2^4\times3^5\times5\times13\).

Step 2

Why this answer is correct

On division, subtract the powers of the same bases, giving \(2^2\times3^3\times5\).

Step 3

Exam Tip

In prime-power division, subtract exponents. चरण 1: महत्तम समापवर्तक \(2^2\times3^2\times13\) और लघुत्तम समापवर्त्य \(2^4\times3^5\times5\times13\) है। चरण 2: भाग देने पर समान आधारों की घातें घटती हैं, इसलिए अनुपात \(2^2\times3^3\times5\) है। चरण 3: अभाज्य घातों में भाग करते समय घातों का घटाव करें।
