यदि (a=3) और (r=5) है, तो \(a_5+a_6\) का मान क्या होगा?
If (a=3) and (r=5), what is the value of \(a_5+a_6\)?
Explanation opens after your attempt
A. (11250)
Concept
\(a_5=3\cdot5^4=1875\) and \(a_6=9375\), so the sum is (11250). In exams, calculate large powers separately.
Why this answer is correct
The correct answer is A. (11250). \(a_5=3\cdot5^4=1875\) and \(a_6=9375\), so the sum is (11250). In exams, calculate large powers separately.
Exam Tip
\(a_5=3\cdot5^4=1875\) और \(a_6=9375\), इसलिए योग (11250) है। परीक्षा में बड़े घातों को अलग-अलग निकालें।
