Answer:


\displaystyle (dy)/(dx) = (-4)/(3x^5)

General Formulas and Concepts:

Calculus

Differentiation

  • Derivatives
  • Derivative Notation

Derivative Property [Multiplied Constant]:
\displaystyle (d)/(dx) [cf(x)] = c \cdot f'(x)

Basic Power Rule:

  1. f(x) = cxⁿ
  2. f’(x) = c·nxⁿ⁻¹

Explanation:

Step 1: Define

Identify


\displaystyle y = ((1)/(x^4))/(3)

Step 2: Differentiate

  1. Derivative Property [Addition/Subtraction]:
    \displaystyle y' = (1)/(3) (d)/(dx) \bigg[ (1)/(x^4) \bigg]
  2. Rewrite:
    \displaystyle y' = (1)/(3) (d)/(dx)[x^(-4)]
  3. Basic Power Rule:
    \displaystyle y' = (1)/(3)(-4x^(-5))
  4. Simplify:
    \displaystyle y' = (-4)/(3x^5)
