Correct Answer

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

Step 1

Concept

Write \(1260=126\times10\).

Step 2

Why this answer is correct

\(126=2\times3^2\times7\) and \(10=2\times5\), so \(1260=2^2\times3^2\times5\times7\).

Step 3

Exam Tip

Combine repeated prime factors into powers at the end. चरण 1: \(1260=126\times10\) लिखें। चरण 2: \(126=2\times3^2\times7\) और \(10=2\times5\), इसलिए \(1260=2^2\times3^2\times5\times7\)। चरण 3: गुणनखंडन में सभी भागों को अंत में एक साथ मिलाकर घात लिखें।
