संख्या 2401 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 2401?

Explanation opens after your attempt
Correct Answer

A. \(7^4\)

Step 1

Concept

(2401) can be written as \(49\times49\).

Step 2

Why this answer is correct

Since \(49=7^2\), \(2401=7^4\).

Step 3

Exam Tip

49 is composite, so write the power of 7 in final prime form. चरण 1: \(2401=49\times49\) लिखा जा सकता है। चरण 2: \(49=7^2\), इसलिए \(2401=7^4\)। चरण 3: 49 संयुक्त है, इसलिए अंतिम अभाज्य रूप में 7 की घात लिखें।
