Question

Please show me the procedure/calculations (especially for the root test and where it converges) for this question. The results are already written but I would like to understand how to find these results.

If not specified otherwise, fill in the blanks with integers (pos-
sibly 0 or negative). A fraction should be reduced (for ex-
ample, is accepted but not ), and if it is negative and the
answer boxes (such as 4) have ambiguity, the negative sign
b
a
is accepted
should be put on the numerator (for example
but is not). log x = loger, not log10 .
Let us study the following series E-0 (n+1)(4+1)
with various x.

This series makes sense also for x C. For x = i√3, calculate
