Answer:


-(4)/(r^8)

Explanation:

Given the expression:


-4r^(-8)s^0

First, any number (except 0) raised to the power of 0 is 1. Thus:


-4r^(-8)s^0=-4r^(-8)*1=-4r^(-8)

Next, apply the negative index law of indices:


a^(-n)=(1)/(a^n)

Therefore:


\begin{gathered} -4r^(-8)=-4* r^(-8) \\ =-4*(1)/(r^8) \\ =-(4)/(r^8) \end{gathered}

The given expression written using positive exponents only is:


-(4)/(r^8)
