There are 1 questions in this calculation: for each question, the 4 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ {x}^{7}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{7}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{7}\right)}{dx}\\=&7x^{6}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 7x^{6}\right)}{dx}\\=&7*6x^{5}\\=&42x^{5}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 42x^{5}\right)}{dx}\\=&42*5x^{4}\\=&210x^{4}\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( 210x^{4}\right)}{dx}\\=&210*4x^{3}\\=&840x^{3}\\ \end{split}\end{equation} \]
