Can you help me with these?

Find the curl of the vector field at the given point. F(x, y, z) = x2zi - 2xzj + yzk; (7, -9, 9) curl F = Find the divergence of the vector field F. F(x, y) = 3x2i + 4y2j Find the divergence of the vector field F. F ( x, y, z) = In( 7x2 + zy2)i + 14xyj + In(zy2 + 722) k F (X, y, Z) = Find the divergence of the vector field F at the given point. F (x, y, z) = xyzi + xz j + 3yz2k; (4, 5, 1)
