संख्या 2401 का अभाज्य गुणनखंडन कौन सा है?
Which is the prime factorisation of 2401?
Explanation opens after your attempt
A. \(7^4\)
Concept
(2401) can be written as \(49\times49\).
Why this answer is correct
Since \(49=7^2\), \(2401=7^4\).
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।
