# Chapter 6 - Applications of Integration - 6.8 Logarithmic and Exponential - 6.8 Exercises - Page 481: 54

$$e{x^{e - 1}} + {e^x}$$

#### Work Step by Step

\eqalign{ & \frac{d}{{dx}}\left( {{x^e} + {e^x}} \right) \cr & {\text{derivative of a sum}} \cr & = \frac{d}{{dx}}\left( {{x^e}} \right) + \frac{d}{{dx}}\left( {{e^x}} \right) \cr & {\text{evaluate the derivative}} \cr & = e{x^{e - 1}} + {e^x} \cr}
