There are 1 questions in this calculation: for each question, the 1 derivative of m is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 4sqrt(-{m}^{2} + 16m - 48) + 4m\ with\ respect\ to\ m：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 4sqrt(-m^{2} + 16m - 48) + 4m\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 4sqrt(-m^{2} + 16m - 48) + 4m\right)}{dm}\\=&\frac{4(-2m + 16 + 0)*\frac{1}{2}}{(-m^{2} + 16m - 48)^{\frac{1}{2}}} + 4\\=&\frac{-4m}{(-m^{2} + 16m - 48)^{\frac{1}{2}}} + \frac{32}{(-m^{2} + 16m - 48)^{\frac{1}{2}}} + 4\\ \end{split}\end{equation} \]
