Consider the integral //D x/ideV where D is the region in the first octant (x Z 0, y 2 0, z 2 0) bounded by the planes x2 = 2, = z and z = 2. a) Write the triple integral as an iterated integral in the order dzdydx. b) Write the triple integral as an iterated integral in the order dxdydz. Then evaluate the integral using this order
