There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ a{x}^{b} + 15x + p\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( a{x}^{b} + 15x + p\right)}{dx}\\=&a({x}^{b}((0)ln(x) + \frac{(b)(1)}{(x)})) + 15 + 0\\=&\frac{ab{x}^{b}}{x} + 15\\ \end{split}\end{equation} \]
