There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 6{x}^{-7} - 4sqrt(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{6}{x^{7}} - 4sqrt(x)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{6}{x^{7}} - 4sqrt(x)\right)}{dx}\\=&\frac{6*-7}{x^{8}} - \frac{4*\frac{1}{2}}{(x)^{\frac{1}{2}}}\\=&\frac{-42}{x^{8}} - \frac{2}{x^{\frac{1}{2}}}\\ \end{split}\end{equation} \]
