There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ lg(5) - lg(2 - 5x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = lg(5) - lg(-5x + 2)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( lg(5) - lg(-5x + 2)\right)}{dx}\\=&\frac{0}{ln{10}(5)} - \frac{(-5 + 0)}{ln{10}(-5x + 2)}\\=&\frac{5}{(-5x + 2)ln{10}}\\ \end{split}\end{equation} \]
