E = - dV/dx

same with respecto y and z

now differentiate line wise and get the ansr.

use partial differential to determine the components of the electric field strength vector.

the electric field strength vector is given by 

E = -k(4xi^ - 2yj^ + 2zk^)

therefore at the point (1, 1, 1) the magnitude of the electric field strength is (24)(1/2).

the ans is-

[(4)^2 +(2)^2+(2)^2]^1\2

i.e.

(24)^1/2
