There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 20{\frac{1}{x}}^{(\frac{3}{4})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 20{\frac{1}{x}}^{\frac{3}{4}}\right)}{dx}\\=&20({\frac{1}{x}}^{\frac{3}{4}}((0)ln(\frac{1}{x}) + \frac{(\frac{3}{4})(\frac{-1}{x^{2}})}{(\frac{1}{x})}))\\=&\frac{-15}{x^{\frac{7}{4}}}\\ \end{split}\end{equation} \]
