There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 5xtan(8{x}^{7})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 5xtan(8x^{7})\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 5xtan(8x^{7})\right)}{dx}\\=&5tan(8x^{7}) + 5xsec^{2}(8x^{7})(8*7x^{6})\\=&5tan(8x^{7}) + 280x^{7}sec^{2}(8x^{7})\\ \end{split}\end{equation} \]
