There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -3e^{x} + e^{4x} - 2e^{5x}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -3e^{x} + e^{4x} - 2e^{5x}\right)}{dx}\\=&-3e^{x} + e^{4x}*4 - 2e^{5x}*5\\=&-3e^{x} + 4e^{4x} - 10e^{5x}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -3e^{x} + 4e^{4x} - 10e^{5x}\right)}{dx}\\=&-3e^{x} + 4e^{4x}*4 - 10e^{5x}*5\\=&-3e^{x} + 16e^{4x} - 50e^{5x}\\ \end{split}\end{equation} \]
