(75) का अभाज्य गुणनखंडन कौन सा है?
Which is the prime factorisation of (75)?
Explanation opens after your attempt
Correct Answer
B. \(3 \times 5^2\)
Concept
Write \(75=3 \times 25\).
Why this answer is correct
Since \(25=5^2\), \(75=3 \times 5^2\).
Exam Tip
Do not leave (25) in the final answer because it is not prime. चरण 1: \(75=3 \times 25\) लिखें। चरण 2: \(25=5^2\), इसलिए \(75=3 \times 5^2\)। चरण 3: (25) को अंतिम उत्तर में न छोड़ें क्योंकि वह अभाज्य नहीं है।
