Question
9. Use logarithmic differentiation to find the derivative of the following functions.

a. \( y = \frac{(\sin(x))^6 (\tan(x))^4}{(x^2 + 3)^2} \)

\[ y' = \boxed{} \]

b. \( y = x^{5x} \)

\[ y' = \boxed{} \]

c. \( y = (\cos(9x))^x \)

\[ y' = \boxed{} \]

d. \( y = (\tan x)^{8/x} \)

\[ y' = \boxed{} \]
