remember that
a^(-b)=(1)/(a^b)

so


a^(-2)b^5=


((1)/(a^2))(b^5)=


(b^5)/(a^2)

b^5 divided by a^2

I don't know how to do the fraction thingy on this thing but to explain it, since a has a negative exponent it has to move to the denominator for this equation to work. That is why the b^2 is on top and the a^2 on the bottone. Once the a^-2 goes to the bottom, it loses the negative sign.
