संख्या 80 का सही अभाज्य गुणनखंडन कौन सा है?
Which is the correct prime factorisation of 80?
Explanation opens after your attempt
Correct Answer
A. \(2^4\times5\)
Concept
(80) can be written as \(16\times5\).
Why this answer is correct
\(16=2^4\), so \(80=2^4\times5\).
Exam Tip
In the final prime factorisation, keep only prime numbers. चरण 1: \(80=16\times5\) लिखा जा सकता है। चरण 2: \(16=2^4\), इसलिए \(80=2^4\times5\)। चरण 3: अंतिम अभाज्य गुणनखंडन में केवल अभाज्य संख्याएं रखें।
