What is the prime factorisation of (120)?
Explanation opens after your attempt
Correct Answer
A. \(2^3 \times 3 \times 5\)
Concept
Write \(120=12 \times 10\).
Why this answer is correct
\(12=2^2 \times 3\) and \(10=2 \times 5\), so \(120=2^3 \times 3 \times 5\).
Exam Tip
Do not forget to combine repeated prime factors from different parts. चरण 1: \(120=12 \times 10\) लिखें। चरण 2: \(12=2^2 \times 3\) और \(10=2 \times 5\), इसलिए \(120=2^3 \times 3 \times 5\)। चरण 3: अलग-अलग भागों के समान अभाज्य गुणनखंडों को जोड़ना न भूलें।
