Correct Answer
A. \(2^3\times3^2\)
Step 1
Concept
Write \(72=8\times9\).
Step 2
Why this answer is correct
\(8=2^3\) and \(9=3^2\), so \(72=2^3\times3^2\).
Step 3
Exam Tip
In prime factorisation, break 8 and 9 into prime powers. चरण 1: \(72=8\times9\) लिखें। चरण 2: \(8=2^3\) और \(9=3^2\), इसलिए \(72=2^3\times3^2\)। चरण 3: अभाज्य गुणनखंडन में 8 और 9 को अलग करके लिखें।
