Answer:
A = 3/2
B = 3
C = 6
D = 12
Step-by-step explanation:
Simply plug it in. When you have a negative exponent, you basically switch the sign of the exponent and put a one over the number itself. 
- So we have 2^-1. This is the same as  = a = a
- Now do  = b = b
- Then do  = c = c
- Finally do  = d = d
