#$21.$ Using Stokes' Theorem, find the value of the line integral $\backslash$int$\_$C F$*$dr$,$ where C goes once around the

intersection of the plane z$=2$y$+$x and the cylinder x$^(2)+$y$^(2)=4,$ in the clockwise direction when viewed

from above, and where

F$($x$,$y$,$z$)=($:z$+$x$^(3),$x$,$y$+$e$^($z$^(2))$:$)$
