Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Write (756) as \(4\times189\).

Step 2

Why this answer is correct

\(4=2^2\) and \(189=27\times7=3^3\times7\), so \(756=2^2\times3^3\times7\).

Step 3

Exam Tip

Break a large number into convenient factors first. चरण 1: (756) को पहले \(4\times189\) के रूप में देख सकते हैं। चरण 2: \(4=2^2\) और \(189=27\times7=3^3\times7\), इसलिए \(756=2^2\times3^3\times7\)। चरण 3: बड़ी संख्या को सुविधाजनक गुणनखंडों में तोड़कर आगे अभाज्य बनाएं।
