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