How would i simply this?

Hello from MrBillDoesMath!
Answer:
1/3
Discussion:
The problem looks complicated until you realize the term n^-4 appears in both the numerator and denominator. Hence their quotient is 1. That is,
n ^(-4) / ( 3 * n^(-4)) =
(n ^(-4) / n^(-4) ) * (1/3) =
1 * (1/3) =
1/3
Thank you,
MrB
