I did the first 2 question you requested, the remaining questions are using the same principles I did. You should at least attempt it and show your working perhaps I can point out your mistakes if you do not get your answer :)

In general, try to expand in the indices first, then apply law 1 and 2 of indices, you may notice how I “remove” the brackets within my first 2 steps (expanding in the indices), thereafter just apply the first 2 law of indices
