4 is not equivalent to 4% or 1/25

Let f(x) = y
thus y =

switch the position of y and x in the equation

then solve for y in this case

∴ y=

Thus,
Answer:
![3\sqrt[3]{x-3}-5](https://tex.z-dn.net/?f=3%5Csqrt%5B3%5D%7Bx-3%7D-5)
Step-by-step explanation:
You can factor out the common term of 27 from 81*
![\sqrt[3]{27(x-3)}-5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%28x-3%29%7D-5)
Separate
![\sqrt[3]{27}\sqrt[3]{x-3}-5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D%5Csqrt%5B3%5D%7Bx-3%7D-5)
Simplify
