Express each of the following as a rational number of the form `p/q`, where `p` and `q` are integers and `q !=0:`
(i)`2^(-3)`
(ii) `(-4)^(-2)`
(iii) `1/(3^(-2))`
(iv)`(1/2)^(-5)`
(v) `(2/3)^(-2)`

Explanation

(i)`2^(-3)``=(1/2)^3=(1/8)`
(ii) `(-4)^(-2)``=(1/16)`
(iii) `1/(3^(-2))``=9`
(iv)`(1/2)^(-5)``=32`
(v) `(2/3)^(-2)``=9/4`
