Hard Mathematics Chapter 1: Real Numbers Class 10 Level 9

यदि \(n=2^{10}\times3^5\times7^4\times13^2\), तो (n) किस संख्या से अवश्य विभाज्य होगा?

If \(n=2^{10}\times3^5\times7^4\times13^2\), by which number must (n) be divisible?

Explanation opens after your attempt
Correct Answer

A. \(2^9\times3^4\times7^3\times13\)

Step 1

Concept

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

Step 2

Why this answer is correct

\(2^9\), \(3^4\), \(7^3\), and 13 are all available in (n).

Step 3

Exam Tip

Therefore, (n) must be divisible by the first option. चरण 1: विभाज्यता के लिए भाजक की घातें दी गई संख्या की घातों से अधिक नहीं होनी चाहिए। चरण 2: \(2^9\), \(3^4\), \(7^3\) और 13 सभी (n) में उपलब्ध हैं। चरण 3: इसलिए (n) पहले विकल्प से अवश्य विभाज्य होगा।
