There are 1 questions in this calculation: for each question, the 15 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 15th\ derivative\ of\ function\ {x}^{9} + {\frac{1}{x}}^{7} - sqrt({x}^{3})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{9} + \frac{1}{x^{7}} - sqrt(x^{3})\\\\ &\color{blue}{The\ 15th\ derivative\ of\ function:} \\=& - \frac{70959641905152000}{x^{22}} + \frac{23717560741875}{32768x^{\frac{27}{2}}}\\ \end{split}\end{equation} \]
