    Derivative

    Hi

    I'm trying to work out the second derivative of the following:

    3x^2 / 2*sqrt(x^3+x^3)

    Can anyone help? Not sure if I need to derive whats in the sqrt also as its the second derivative?

    3x^2 / 2*sqrt(x^3+x^3)
    I'm assuming the given expression is ...

    \frac{3x^2}{2\sqrt{x^3 + x^3}} = \frac{3x^2}{2\sqrt{2x^3}} = \frac{3}{2\sqrt{2}} \cdot \sqrt{x}

    correct?
