V=−x^{2} y−xz^{3} +4 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\ \\  E =  -  \frac{∂v}{∂x}i -  \frac{∂v}{∂y}j -  \frac{∂v}{∂z}k  \\ \\ now \:  \frac{∂v}{∂x} =  - 2xy -  {z}^{3}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\   \\ \frac{∂v}{∂y} =  -  {x}^{2}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \frac{∂v}{∂x} =  -  {3xz}^{2}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\ \\  hence \\ \\  E=(2xy+z ^{3} )i+x ^{2} j+3xz ^{2} k
