Answer 2

You coudl just add up the terms using a calculator. Are you allowed one?

Answer 3

Yes, this is just a like a bank of practice homework questions there is nothing you can't do. I don't know how you put it in the calculator though @AlexBabich

Answer 4

Answer 5

that will be a common term mutiplied to each 5^n-1 so you can factor it out from the very beginning

Answer 6

something like 3/25 ( 5^(1-1) + 5^(2-1) + ... + 5^(8-1) )
