Question Hard Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 7

यदि \(20736=2^m\times3^4\), तो (m) का मान क्या है?

If \(20736=2^m\times3^4\), what is the value of (m)?

Explanation opens after your attempt
Correct Answer

A. 8

Step 1

Concept

(20736) can be written as \(256\times81\).

Step 2

Why this answer is correct

\(256=2^8\) and \(81=3^4\), so \(20736=2^8\times3^4\).

Step 3

Exam Tip

Comparing gives (m=8). चरण 1: \(20736=256\times81\) लिखा जा सकता है। चरण 2: \(256=2^8\) और \(81=3^4\), इसलिए \(20736=2^8\times3^4\)। चरण 3: तुलना करने पर (m=8) है।
