    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ third\ derivative\ of\ function\ {x}^{2}{e}^{7}x\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{3}e^{7}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{3}e^{7}\right)}{dx}\\=&3x^{2}e^{7} + x^{3}*7e^{6}*0\\=&3x^{2}e^{7}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 3x^{2}e^{7}\right)}{dx}\\=&3*2xe^{7} + 3x^{2}*7e^{6}*0\\=&6xe^{7}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 6xe^{7}\right)}{dx}\\=&6e^{7} + 6x*7e^{6}*0\\=&6e^{7}\\ \end{split}\end{equation} \]
