Answer:
Step-by-step explanation:
16x^4y^-3z^4 / 36x^-2yz^0
16x^4y^-3z^4 = 16x^4z^4/y^3
36x^-2yz^0 = 36x^-2y(1) =36x^-2y = 36y/x^2
16x^4y^-3z^4 / 36x^-2yz^0
= (16x^4z^4/y^3) / (36y/x^2)
= 16x^4z^4/y^3 * x^2/36y
= (4/9)x^6z^4/y^4
or another way
fist multiply it out
f(x) = 4x^(3/5) - x^(8/5)
now differentiate knowing d/dx(x^n) = n x^(n-1)
to get
4*(3/5) x^(-2/5) - 8/5 x^(3/5)
simplify to get
12/5/x^(2/5) - 8/5 x^(3/5)
If this is what your looking for please give me brainiest, i have done this problem in the past so i know how to solve it :)

Answer:
D) ![-\sqrt[3]{x-1}](https://tex.z-dn.net/?f=-%5Csqrt%5B3%5D%7Bx-1%7D)
Step-by-step explanation:
-the function is the cube root
-the cube root of zero is zero
- the graph is at 0 when x = 1, thus "x-1" must be part of answer
- the cube root of -8 is -2, at -8 the graph is +2. so the function is negated
![-\sqrt[3]{x-1}](https://tex.z-dn.net/?f=-%5Csqrt%5B3%5D%7Bx-1%7D)
