How do I evaluate the following sum:
∞∑m=1∞∑k=1m(−1)m(−1)klog(m+k)(m+k)3
Note I used many idea such as :Hochino's Idea and taylor expansion of
log(1+x) at x=1 where x=km ,but those methods not work .
and also i tried to write log(m+k) as a power series but it became to me as a
triple series then it is very complicated for evaluation !!!
Thank you for any help
