Consider the region bounded by the curve $()/((8$ x$^(3)$ e$^(-$x$^(2))/))$ and the $()/(($ x $/))-$axis, between $()/(($ x$)=0/)$ and $()/(($ x$)=2\mathrm{.}6/).$

Set up and solve the integral representing the area of the given region. Hint: the previous homework problem did most of the work. Now just evaluate as described by the fundamental theorem of calculus.

Area $()/(()=/)$

units squared

$($Give the exact answer. You'll need to use exponent base e in your answer$)$

Next, round your answer to $6$ decimal places:

Area $()/((/$approx $/))$
