Set up an integral in spherical coordinates to evaluate ${}_E\frac{8}{x^2{y}^2{z}^2}dV,$ where $E$ is the region bounded by the spheres $x^2{y}^2{z}^2=1$ and $x^2{y}^2{z}^2=4$ in the octant given by and

Choose values from the domains: $0,02,$ and $0.$ Enter rho to denote $,$ theta to denote $,$ phi to denote $,$ and pi to denote $.$
