g(x) = x^2
h(x) = 5x
(hog)(x) = 5x^2
5(25)^2
5(625)
3125

g(x) is the square root function:  g(x) = sqrt(x).
h(x) is the equation of a straight line:  h(x) = 5x.

Then the composite function h( g(x) ) is 5(sqrt(x) ).
If the input to this function is 25 (as shown in the problem), the output of g(x) is 5.  This 5 becomes the input of h(x) , which takes on the value 1.

So the answer here is  h( g(25) ) = 1
