Pay attention to the procedure:
(5(10)^2)^3/(10(5))^4. What we need is plug in the corresponding x and y values
Then you have to do x squared before you multiply it by 5 like this:
(5(100))^3/(10(5))^4
Now solve for what is in the top parenthesis.
(500)^3/(10(5))^4
500^3=125000000
Now work on the denominator.
Do what is inside the parenthesis first
10*5=50
Now (50)^4=6250000
Now divide the numerator and the denominator.
125000000/6250000
Which equals 20, Please check if I'm wrong but I think this is what you need 

Answer: The answer is option D i.e. 20

Step-by-step explanation:

We have the expression

((5x^2) ^3)/(10y)^4

and values of x=10, y=5

Putting the values of x and y in the expression

((5×10^2)^3)/ (10×5)^4

= (5×100)^3/(50^4)

= (500^3)/6250000

125000000/6250000

= 20

So the expression (5x^2)^3/(10y)^4  is evaluated to 20
