There are 1 questions in this calculation: for each question, the 5 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 5th\ derivative\ of\ function\ 4{\frac{1}{x}}^{5} + 7{\frac{1}{x}}^{4} - \frac{2}{x} + 12\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{4}{x^{5}} + \frac{7}{x^{4}} - \frac{2}{x} + 12\\\\ &\color{blue}{The\ 5th\ derivative\ of\ function:} \\=&\frac{-60480}{x^{10}} - \frac{47040}{x^{9}} + \frac{240}{x^{6}}\\ \end{split}\end{equation} \]
