Answer:
I hope this helps-How to define a logarithmic unction-
Step-by-step explanation:
Therefore, the (multiple-valued) logarithmic function of a nonzero complex variable z=reiΘ is defined by the formula logz=lnr+i(Θ+2nπ)(n∈Z).
Some basic properties of the function logz are the following:
log(z1z2)=logz1+logz2.
log(z1z2)=logz1−logz2.
There may hold Log(z1z2)≠Logz1+Logz2.
