Write an integral in the form $A={\displaystyle \underset{a}{\overset{b}{}}}h(x)dx$ such that A expresses the area of the region between the functions $y=e^{2\mathrm{.}5x},y=e^{8x-1}$ and $x=0.$ Evaluate the integral to find the area of the region. Answers should be exact. As a suggestion, graph the equations so you can see the region for which you are solving for the area.
