I've done the LHS partcould u tell me how to do the RHS partsurfaceMany thanks

Verify the divergence theorem (i.c. show in the mathematical statement of the theorem that LHS = RHS ) for the vector field A - 2xzi + zx2j + (z2 - xyz + 2)k, and the region in z 2 0 enclosed by x2 + y2 + 4z2 = a2 with a > 0
