the "+...+64" is not under the radical sign. Just 2)2. and the "..." is in the question, I don't know what it stands for. I am at a complete loss with these two questions. and my math book doesn't go into enough detail with these types of equations.
1. 1. Find the exact(no approximations)sum for the finite series
S sub n= (2 + 2 + 2(2+...+64
i used the parentheses to represent a radical sign
2. Show that the sum of the first 10 terms of the geometric series
1 + 1/3 + 1/9 + 1/27+...
is twice the sum of the first 10 terms of...
