What are they actually asking me to find here?

[Dell]

i am asked to present this function as a number of simple functions

f(x)=4*$$\sqrt[3]{cot^8(7x)}$$

what i did was

f(x)=4*$$\sqrt[3]{cot⁸(7x)}$$
=4*(cos7x/sin7x)^8/3

a(x)=cos(7x)
b(x)=sin(7x)
c(x)=x⁸
d(x)=$$\sqrt[3]{x}$$

f(x)=4*d(c(a(x)/b(x)))

but that just seem stupid to me, do you think that that's what I am meant to do??

Well, i guess that depends on what u call simple functions.
