Expert Mathematics Chapter 1: Real Numbers Class 10 Level 8

यदि \(n=2^9\times3^4\times5^5\times13^2\), तो (n) किस संख्या से अवश्य विभाज्य होगा?

If \(n=2^9\times3^4\times5^5\times13^2\), by which number must (n) be divisible?

Explanation opens after your attempt
Correct Answer

A. \(2^8\times3^4\times5^4\times13^2\)

Step 1

Concept

For divisibility, the exponents of the divisor must not exceed those in the number.

Step 2

Why this answer is correct

In the first option, all exponents are less than or equal to those in (n).

Step 3

Exam Tip

Therefore, (n) must be divisible by that number. चरण 1: विभाज्यता के लिए भाजक की घातें संख्या की घातों से अधिक नहीं होनी चाहिए। चरण 2: पहले विकल्प में सभी घातें (n) की घातों से कम या बराबर हैं। चरण 3: इसलिए (n) उस संख्या से अवश्य विभाज्य होगा।
