Explanation opens after your attempt
Correct Answer
A. \(2^5\times3^3\times5\times7\)
Concept
Write \(30240=32\times945\).
Why this answer is correct
\(945=3^3\times5\times7\), so \(30240=2^5\times3^3\times5\times7\).
Exam Tip
Do not keep 945 in the final answer. चरण 1: \(30240=32\times945\) लिखें। चरण 2: \(945=3^3\times5\times7\), इसलिए \(30240=2^5\times3^3\times5\times7\)। चरण 3: 945 को अंतिम उत्तर में न रखें।
