The small numbers in math shows that you have to mutiplies how much the power is. For Example, 5 with a power of 2 → 5² that's what it looks like.
We have been given the function 
Convert this expression in difference of cubes form.

Now, in order to find the factors, we can apply the difference of cubes form, which is given by

On applying this formula, we get

Hence, the factors of the given expression are

Out of the given option, A is the correct option.
x^5 − 4 is the required factor.
Answer:
7/20
Step-by-step explanation:
Since y varies directly with x, the ratio of y to x is proportional.
... y / 7 = (1/4)/(5)
... y / 7 = 1 / 20 . . . . simplify
... y = 7/20 . . . . . multiply by 7
