I Can Help You In Them After NTSE As I Dont Have Much time to spend on brilliant. but still for 3rd problem you can factorize the denominator as follows and then apply telescoping sum a^4+a^2+1 = (a^2+a+1)(a^2-a+1) for 6th one you can write general term of the progression and apply sigma notation for rest please wait till 10th may i will surely help you after that
