Find in index notation


I know this is a simple case of substitution but i'm not sure how this can be expressed in index notation. Any help appreciated.

First of all substitute a, b and c in

and then i'll show you below

(2^4/5^4)/(-1^3/3^3)x(3^4/5^4)

you can eliminate 5^4 from top and bottom as the cancel out
you then also eliminate 3^3 and the 3^4 becomes 3^1

multiply the rest of them together and you get 2^4/-3
and then it becomes 2^4 x -3^-1

since (1/-3) = -3^-1

the answer would be -16/3 but because you have to express it in index notation therefore its 2^4 x -3^-1
