log(−2)=log(−1)+log(2)                     =log(e^(iπ) )+log(2)                         =log(e^(i(2kπ+π)) )+log(2)                      =iπ(2k+1)+log(2)    {k∈Z}  Is  this a solution???????  I am not sure
log(2)=log(1)+log(2)=log(eiπ)+log(2)=log(ei(2kπ+π))+log(2)=iπ(2k+1)+log(2){kZ}Isthisasolution???????Iamnotsure

ln(−2) =ln(−1)+ln(2)  ln(e^(i(π+2kπ)) )+ln(2)  =ln2 +i(2k+1)π    (k∈Z)
ln(2)=ln(1)+ln(2)ln(ei(π+2kπ))+ln(2)=ln2+i(2k+1)π(kZ)
