Higher Order Derivatives Logarithmic Functions

Find dy/dx for
y = 3^2x+5 

• dy/dx = 3^(2x+4)
• dy/dx = (3^(2x+4)) ln 3
• dy/dx = 3^(2x+5) ln3
• dy/dx = (3^(2x+5)) (ln 3) (2)

Differentiate:
f(x) = x³e^4x
*You will need to remove the Greatest Common Factor

• f '(x) = 3x²e^4x
• f '(x) = 3x²e^4x+3x²e^4x
• f '(x) = x²e^4x(4x+3)
• f '(x) = xe^4x(4x²+3x)
