Question

Cound someone please help me on this, I'm stuck. ​

Answer 1

Negative exponents work like this:

`a^(-b)=(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)=(1)/(8^3)=(1)/(512)`

`(-4)^(-5)=(1)/((-4)^5)=-(1)/(1024)`

`2k^(-4)=(2)/(k^4)`

You can work out the rest applying this logic.
