Negative exponents work like this:

$a^{-b}=\dfrac{1}{a^b}$

So, in order to evaluate a negative exponent, you simply have to invert the base, and then raise to the positive equivalent of the exponent.

As an example, here are the first three exercises:

$8^{-3}=\dfrac{1}{8^3}=\dfrac{1}{512}$

$(-4)^{-5}=\dfrac{1}{(-4)^5}=-\dfrac{1}{1024}$

$2k^{-4}=\dfrac{2}{k^4}$

You can work out the rest applying this logic.
