    Product Rule (Derivative)

    Differentiate a product of two power functions: f(x) = xᵃ and g(x) = xᵇ at a given x.

    Standard Formula
    d/dx[f·g] = f'·g + f·g'

    Worked Example: Product Rule (Derivative)

    Given:

    • a = 2
    • b = 3
    • x = 1
    1. f=x², g=x³
    2. f'=2x, g'=3x²
    3. d/dx = 2x·x³ + x²·3x² = 2x⁴+3x⁴ = 5x⁴
    4. At x=1: 5
