1. -2m^2 n^-3 /(mn^-2)^2

2. (-2pq)^-2 / 2pq^-2

For number 1, I don't have any idea but for number 2, I arrived at 1/2p. Is that right? Thanks much in advance.

-2m^2 n^-3 /(mn^-2)^2

-2m^2 n^-3 /(m^2n^-4)

-2m^(2-2) n^(-3+4)

-2n

#2.

(-2pq)^-2 / 2pq^-2

(-2)^-2 p^-2 q^-1 / 2pq^-2

1/8 p^(-2-1) q^(-1+2)

q/8p^3
