यदि (a=5) और (r=4) है, तो \(a_5+a_6\) का मान क्या होगा?
If (a=5) and (r=4), what is the value of \(a_5+a_6\)?
Explanation opens after your attempt
B. (6400)
Concept
\(a_5=5\cdot4^4=1280\) and \(a_6=5120\), so the sum is (6400). In exams, calculate large powers separately.
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.
Exam Tip
\(a_5=5\cdot4^4=1280\) और \(a_6=5120\), इसलिए योग (6400) है। परीक्षा में बड़े घातों को अलग-अलग निकालें।
