There are 1 questions in this calculation: for each question, the 4 derivative of a is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ {a}^{4}\ with\ respect\ to\ a：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = a^{4}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( a^{4}\right)}{da}\\=&4a^{3}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 4a^{3}\right)}{da}\\=&4*3a^{2}\\=&12a^{2}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 12a^{2}\right)}{da}\\=&12*2a\\=&24a\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( 24a\right)}{da}\\=&24\\ \end{split}\end{equation} \]
