Correct Answer

B. (6400)

Step 1

Concept

\(a_5=5\cdot4^4=1280\) and \(a_6=5120\), so the sum is (6400). In exams, calculate large powers separately.

Step 2

Why this answer is correct

The correct answer is B. (6400). \(a_5=5\cdot4^4=1280\) and \(a_6=5120\), so the sum is (6400). In exams, calculate large powers separately.

Step 3

Exam Tip

\(a_5=5\cdot4^4=1280\) और \(a_6=5120\), इसलिए योग (6400) है। परीक्षा में बड़े घातों को अलग-अलग निकालें।
