Correct Answer
A. \(2^2\times3^2\times5\times7^2\)
Concept
Write \(8820=180\times49\).
Why this answer is correct
\(180=2^2\times3^2\times5\) and \(49=7^2\), so \(8820=2^2\times3^2\times5\times7^2\).
Exam Tip
Convert 180 and 49 into prime powers. चरण 1: \(8820=180\times49\) लिखें। चरण 2: \(180=2^2\times3^2\times5\) और \(49=7^2\), इसलिए \(8820=2^2\times3^2\times5\times7^2\)। चरण 3: 180 और 49 को अभाज्य घातों में बदलें।
