don't you think this is cutting it a bit close. asking for help 2 hours before an exam?the polar form of a complex number is:

where and (usually)

find and simplify with and in their polar forms. then convert back to formb) evaluate z^3/w^7 in form a+ib

see post #4 herec) find all cube roots of z leaving answers in polar form

of course, we would write instead of as was done there

try them and tell me what you get. it will be good practice for that exam of yours
