minta tolong dikerjakan

itu jawaban nya di kunci jawaban ada kok

a = 1/2 b = 2 c = 1

a^(-2)bc^3
--------------- =
ab^2c^(-1)

(1/2)^(-2) (2)(1)^3
----------------------- =
(1/2)(2)^2 (1)^(-1)

(1/2)^(-2-1) (2)^(1-2) (1)^(3-(-1)) =

(1/2)^(-3) (2)^(-1) (1)^(3+1) =

2^3 (1/2)^1 (1)^4 =

8 (1/2) (1) =

8/2 =

4
