There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ log_{\frac{7}{10}}^{\frac{4}{5}}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( log_{\frac{7}{10}}^{\frac{4}{5}}\right)}{dx}\\=&(\frac{(\frac{(0)}{(\frac{4}{5})} - \frac{(0)log_{\frac{7}{10}}^{\frac{4}{5}}}{(\frac{7}{10})})}{(ln(\frac{7}{10}))})\\=&\frac{0}{4}\\ \end{split}\end{equation} \]
