Answer 1

C)  (-3)⁻² = 1 / (-3)²  =1/9;
d)  (-3)⁻³  = 1 / (-3)³ =1/-27 =-1/27;
e)  (1/2) ⁻² =1/ (1/2)² =  1/ 1/4 =4;
f)  (1/2)⁻⁵ = 1/ (1/2)⁵= 1/ 1/32= 32;
g) (2/3)⁻² = 1/ (2/3)² = 1/ 4/9 = 9/4 = 2 i 1/4;
h) (-2/3)⁻⁴ = 1/(-2/3)⁴  = 1 / 16/81 =81/16 = 5 i 1/16;
i)  (0,2)⁻² = (1/5)⁻² = 1/(1/5)² =1/ 1/25 = 25;
j)  (-0,2)⁻³ =(-1/5)⁻³ = 1/ (-1/5)³ = 1/ -1/125 = -125;
