There are 1 questions in this calculation: for each question, the 5 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 5th\ derivative\ of\ function\ 0.0002{x}^{6} - 0.0065{x}^{5} + 0.0821{x}^{4} - 0.442{x}^{3} + 0.6645{x}^{2} + 2.1286x + 20.404\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.0002x^{6} - 0.0065x^{5} + 0.0821x^{4} - 0.442x^{3} + 0.6645x^{2} + 2.1286x + 20.404\\\\ &\color{blue}{The\ 5th\ derivative\ of\ function:} \\=&0.144x - 0.78\\ \end{split}\end{equation} \]
