WOW well first u would start your way well find what is in the parentheses like do n+1 and work your way up. Remember PEMDAS
Parentheses
Exponents

So far I got it down to ((4/3)n^3+(11/6)n^2)/((4/3)n^3)+(2n^2)+(2/3)n.

Would I be able to cancel out the ((4/3)n^3)? So that it would be ((11/6)n^2)/((2n^2)+(2/3)n)?

Or can I simplify that even futher by combining the n^2s?
