Question

Need help solving this derivatives problem.

Answer 1

`f^((4))(x)=-(12)/(x^2)\\\\f^((5))=(24)/(x^3)`

Explanation:

Correct so far.

For the next derivatives, the power rule applies.

4th derivative = (d/dx)(12x^-1) = -12x^-2 = -12/x^2

5th derivative = (d/dx)(-12x^-2) = (-2)·(-12)·x^-3 = 24/x^3
