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