Homework Statement
n / 8^n
Homework Equations
The Attempt at a Solution
It converges to 8 / 49? Not sure how.
First test of divergence
lim n-> n / 8^n. infinity / infinity = 1. BUT bottom grows fast.
Using L`Hospital
lim n -> 1 / 3*8^n*ln(2) ---> goes to 0
Tried to use the ratio test
[ 1 / 3*8^(n+1)*ln(2) ] * [ 3*8^n*ln(2) ]
1/8 is left from the ratio test
