There are 1 questions in this calculation: for each question, the 7 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 7th\ derivative\ of\ function\ \frac{{x}^{4}}{(1 + {x}^{3})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{x^{4}}{(x^{3} + 1)}\\\\ &\color{blue}{The\ 7th\ derivative\ of\ function:} \\=&\frac{-11022480x^{18}}{(x^{3} + 1)^{8}} + \frac{36741600x^{15}}{(x^{3} + 1)^{7}} - \frac{46131120x^{12}}{(x^{3} + 1)^{6}} + \frac{26671680x^{9}}{(x^{3} + 1)^{5}} - \frac{6849360x^{6}}{(x^{3} + 1)^{4}} + \frac{594720x^{3}}{(x^{3} + 1)^{3}} - \frac{5040}{(x^{3} + 1)^{2}}\\ \end{split}\end{equation} \]
