Hard Mathematics Chapter 1: Real Numbers Class 10 Level 9

यदि \(n=2^8\times3^6\times5^4\times11^2\), तो (n) किस संख्या से विभाज्य नहीं होगा?

If \(n=2^8\times3^6\times5^4\times11^2\), by which number will (n) not be divisible?

Correct Answer

A. \(11^3\)

Step 1

Concept

Every prime power of a divisor must be available in the number.

Step 2

Why this answer is correct

(n) has power 2 of 11, but \(11^3\) needs power 3.

Step 3

Exam Tip

Therefore, (n) is not divisible by \(11^3\). चरण 1: भाजक की हर अभाज्य घात संख्या में उपलब्ध होनी चाहिए। चरण 2: (n) में 11 की घात 2 है, पर \(11^3\) के लिए घात 3 चाहिए। चरण 3: इसलिए (n), \(11^3\) से विभाज्य नहीं होगा।
