Hard Mathematics Chapter 1: Real Numbers Class 10 Level 4

यदि \(n=2^4\times3\times5^2\), तो (n) निम्न में से किससे विभाज्य नहीं होगा?

If \(n=2^4\times3\times5^2\), by which of the following will (n) not be divisible?

Explanation opens after your attempt
Correct Answer

C. 48

Step 1

Concept

In (n), the powers are \(2^4\), \(3^1\), and \(5^2\).

Step 2

Why this answer is correct

\(48=2^4\times3\), so divisibility by 48 is possible.

Step 3

Exam Tip

\(80=2^4\times5\), \(75=3\times5^2\), and \(150=2\times3\times5^2\) are also present; hence all given options divide (n). चरण 1: (n) में 2 की घात 4, 3 की घात 1 और 5 की घात 2 है। चरण 2: 48 का गुणनखंडन \(2^4\times3\) है, इसलिए 48 से विभाज्यता संभव है। चरण 3: 80 का गुणनखंडन \(2^4\times5\), 75 का \(3\times5^2\), और 150 का \(2\times3\times5^2\) भी मौजूद हैं; इसलिए दिए गए सभी विभाज्य हैं।
