Answer:

2nd option

Explanation:

Using the power rule


(d)/(dx) (a
x^(n) ) = na
x^(n-1)

Given

f(x) =
\frac{3}{2\sqrt[3]{x} } =
\frac{3}{2x^{(1)/(3) } } =
(3)/(2)
x^{-(1)/(3) } , then

f'(x) = -
(1)/(3) ×
(3)/(2)
x^{-(4)/(3) }

= -
(1)/(2) ×
\frac{1}{x^{(4)/(3) } }

= -
\frac{1}{2x^{(4)/(3) } } = -
\frac{1}{2\sqrt[3]{x^4} } [ Note there should be a leading negative ]
