There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (ax - 1)(ax - 1)(ax - 1)(ax - 1)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = a^{4}x^{4} - 4a^{3}x^{3} + 6a^{2}x^{2} - 4ax + 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( a^{4}x^{4} - 4a^{3}x^{3} + 6a^{2}x^{2} - 4ax + 1\right)}{dx}\\=&a^{4}*4x^{3} - 4a^{3}*3x^{2} + 6a^{2}*2x - 4a + 0\\=&4a^{4}x^{3} - 12a^{3}x^{2} + 12a^{2}x - 4a\\ \end{split}\end{equation} \]
