Correct Answer

B. (6)

Step 1

Concept

\(8\cdot3^{n-1}=1944\), so \(3^{n-1}=243=3^5\) and (n=6). Compare powers.

Step 2

Why this answer is correct

The correct answer is B. (6). \(8\cdot3^{n-1}=1944\), so \(3^{n-1}=243=3^5\) and (n=6). Compare powers.

Step 3

Exam Tip

\(8\cdot3^{n-1}=1944\), इसलिए \(3^{n-1}=243=3^5\) और (n=6)। घातों की तुलना करें।
