Homework Statement
Find the sum of 9 terms of the series 3 + 3^(4/3) + 3^(5/3) + ...
Homework Equations
I'm just learning sequences and series and senior high school level. I'm finding it hard to apply a, ar, ar^(n-1), ... to this.
a = 3.
I don't know how to find common ratio. I'm confused. Once I know r I can apply the standard formula for summing the series.
The Attempt at a Solution
Any help will be greatly appreciated.
