Correct Answer

A. \(2\times3^5\)

Step 1

Write \(486=2\times243\).

Step 2

Why this answer is correct

Since \(243=3^5\), \(486=2\times3^5\).

Step 3

Exam Tip

Do not leave 243 in the final answer; write it as a power of 3. चरण 1: \(486=2\times243\) लिखें। चरण 2: \(243=3^5\), इसलिए \(486=2\times3^5\)। चरण 3: 243 को अंतिम उत्तर में न छोड़कर 3 की घात में लिखें।
