Hello!
Notice that we have a series and we have to write it using sigma notation.
Let's analyze it:
• It starts with just the number 9, then a fraction is added and from there the exponents appear in crescent order.
Knowing it, we can write it as:
If we solve it, we will obtain:
[tex]9+3+1+\frac{1}{3}+\frac{1}{9}+\frac{1}{27}=\frac{364}{27}[/tex]
Final answer: 364/27.
