Answer:
EF = ~3.8
Step-by-step explanation:
Apply the sine theorem:
EF/sinD = DE/sinF
=> EF = DE*(sinD/sinF)
          = 3*(sin75/sin50)
          =3.78 = ~3.8
Hope this helps!
 
        
             
        
        
        
Part 1: 
A.53 =53 
B.3^5/3^-6 =177147
C.(1/4)^3 • (1/4)^2 = 1
/1024
D.(-7)^5/(-7)^7 = 1/49
I tried my best for part 2 but i'm pretty sure it's not right. I think 1/1024 and 1/49 has a value between 0 and 1
