Answer 3

Let's simplify the expression step by step:

1. Start by expanding the square of the first term using the identity (a-b)^2 = a^2 - 2ab + b^2:

(a^-n - a^n)^2 = a^-2n - 2a^0 + a^2n = a^-2n - 2 + a^2n

2. Distribute the -a^2n to get:

(a^-n - a^n)^2 - a^2n(1 + a^-4n) = a^-2n - 2 + a^2n - a^2n - a^-2n = -2

Therefore, the expression simplifies to -2.
