Correct Answer

B. छठा पद(6)th term

Step 1

Concept

From \(8\cdot4^{n-1}=8192\), \(4^{n-1}=1024=4^5\), so (n=6). In exams, equate powers to find (n).

Step 2

Why this answer is correct

The correct answer is B. छठा पद / (6)th term. From \(8\cdot4^{n-1}=8192\), \(4^{n-1}=1024=4^5\), so (n=6). In exams, equate powers to find (n).

Step 3

Exam Tip

\(8\cdot4^{n-1}=8192\) से \(4^{n-1}=1024=4^5\), इसलिए (n=6) है। परीक्षा में घातों को बराबर करके (n) निकालें।
