Correct Answer

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

Step 1

Concept

Write \(180=18\times10\).

Step 2

\(18=2\times3^2\) and \(10=2\times5\), so \(180=2^2\times3^2\times5\).

Step 3

Exam Tip

Change all composite factors into prime form. चरण 1: \(180=18\times10\) लिखें। चरण 2: \(18=2\times3^2\) और \(10=2\times5\), इसलिए \(180=2^2\times3^2\times5\)। चरण 3: सभी संयुक्त गुणनखंडों को अभाज्य रूप में बदलें।
