Answer:
a) we know that this is convergent.
b) we know that this might not converge.
Step-by-step explanation:
Given the 
is convergent
Therefore,
(a) 
The power series 
has radius of convergence at least as big as 8. So we definitely know it converges for all x satisfying -8<x≤8. In particular for x = -3
∴ is convergent.
(b) 
-8 could be right on the edge of the interval of convergence, and so might not converge
Answer: the answer is B
Step-by-step explanation:
= it is equal to because the absolute value of |-5| is 5
It’s definitely E. I say this because there is no correct answer.
Answer:
Very top one
