(a^2^n - a^n - 6) / (a^n + 8)  that's a power of 2n the 2n is an exponent 

Using long division, we have



The parenthesis are the result of what we multiply (a^n+8) by (we multiply it by the top expression - we start with a^2 then -1), and what's not is the result of adding the parenthesis to the expression about that.

Our final result is (a^n+8)*(a^2-1)-8a^2-14

The answer to this question is c
