To be honest I just put this in a calculator. Just remember that 2 is square root, and 3 is cubed root.
The terms in the series are

The series converges, so we
. All the terms in this particular series are known to be positive, so
-th partial sum of the series,

Multiply both sides by
:

Subtracting this from
eliminates all the
terms between
and
, leaving us with

As
, the
term will converge to zero, and the value of the infinite series is

Now, we're given

By substitution, we have

so that

Then the sum of the first 8 terms is

and the difference between this and the infinite sum is
