There are 1 questions in this calculation: for each question, the 4 derivative of g is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ (l - 1)(o - 1)(g - 1)\ with\ respect\ to\ g：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = log - lo - lg + l - og + o + g - 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( log - lo - lg + l - og + o + g - 1\right)}{dg}\\=&lo + 0 - l + 0 - o + 0 + 1 + 0\\=&lo - l - o + 1\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( lo - l - o + 1\right)}{dg}\\=&0 + 0 + 0 + 0\\=&0\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 0\right)}{dg}\\=&0\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( 0\right)}{dg}\\=&0\\ \end{split}\end{equation} \]
