We are given (xy)^(-3).
This leads to 1/(xy)^3.
You see, going from the top to the bottom alters the sign of the exponent to its opposite.
ANSWER: 1/(x^3•y^3)

Answer:
Option B is correct
Step-by-step explanation:
We need to find g(h(f(x)) 
We first find h(f(x))
f(x) = x-3/x
Putting value of f(x) in place of x in h(x) 
h(x) = 2x+1
h(f(x)) = 2(x-3/x) + 1
          = 2(x-3/x) + 1
          = 2x -6 /x +1
          = 2x-6 +x/x
          = 3x-6/x
Now, putting value of h(f(x)) in g(x)
g(x) = x+3
g(h(f(x)))= (3x-6/x) + 3
             = 3x-6/x + 3
             = 3x-6+3x/x
             = 6x-6/x   
So, Option B is correct.
 
        
             
        
        
        
You could make circle like apples until you get all of them I hope this is right
