Correct Answer

A. \(2\times3^3\times5\times7^2\)

Step 1

Concept

Write \(13230=270\times49\).

Step 2

Why this answer is correct

\(270=2\times3^3\times5\) and \(49=7^2\), so \(13230=2\times3^3\times5\times7^2\).

Step 3

Exam Tip

Do not keep 270 and 49 in the final form. चरण 1: \(13230=270\times49\) लिखें। चरण 2: \(270=2\times3^3\times5\) और \(49=7^2\), इसलिए \(13230=2\times3^3\times5\times7^2\)। चरण 3: 270 और 49 को अंतिम रूप में न रखें।
