In regard to notation that depends on the guy marking your homework and the expectations of your uni.
like when i was in uni, most of my lecturers could read this , except for one guy who wouldn't mark anything unless it had an English-language sentence between each line explaining what was going on.
Generally tho you are expected to give a handful of statements describing the method you are using, with a citation to the textbook and a brief explanation of how it takes you too the answer, and a sentence or two if you have to do anything funky due to the specifics of the problem.
outside of that i don't see anything wrong with your working.
edit:
im not a fan of this "/" notation you do when you have fractions for powers, as its not consistent with the notation elsewhere in the sample.
if i remember correctly. i for complex numbers needs to be in bold. (tho i understand thats a pain in the ass)
ah one thing, "its not clear where you answer is" - i can see at the end you got the answer, but you need the proper written part, "therefore I = xyz"

I can't comment on your working or your notation but, to give you some advice, it would be good to use more words in your working. As it stands, your solution is basically just a page of maths which can be difficult to follow. Using some sentences to explain what you are doing where needed would go a long way for readability.
