There are 1 questions in this calculation: for each question, the 9 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 9th\ derivative\ of\ function\ 9{x}^{9} + 8{x}^{8} + 7{x}^{7} + 6{x}^{6} + 5{x}^{5} + 4{x}^{4} + 3{x}^{3} + 2{x}^{2} + x\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 9x^{9} + 8x^{8} + 7x^{7} + 6x^{6} + 5x^{5} + 4x^{4} + 3x^{3} + 2x^{2} + x\\\\ &\color{blue}{The\ 9th\ derivative\ of\ function:} \\=&3265920\\ \end{split}\end{equation} \]
