    you dont need the product rule, all you need is chain

    e^x's derivative is e^x so consider x = x^5-4x

    which becomes your inside function that you take the derivative and multiply it by

    \[e^{x^5−4x}(20x^3+(5x^4−4)^2)\] I made a mistake... this is it

    thats wrong. You are making it more complicated then it has to be Its just the derivative times the inside. Hes just entering it wrong Im pretty sure

    No, you must use the product rule to find second derivative.
