1. The problem statement, all variables and given/known data ∫ (a^(n+1)-1)/(a-1) da 2. Relevant equations i took this equation from the series of sigma with the bound of N k=0 and the argument as a^K (I'm sorry if this is confusing i don't know how to type it out and I'm not sure what all the correct terminology is). 3. The attempt at a solution i really just don't know where to start with this one, i don't know what would be appropriate to use, by parts or substitution, and if it is by substitution what do i substitute?
