electric dipole

None

an electric dipole located at origin in free space has a moment 3i - 2j +k . find potential at a point (2,3,4)

I think Potential at a point due to a dipole can be worked when the dipole is at the origine and the length of the dipole is small,with the equation

V = (K P Cos x)/ r^2

K= 9X10^9, P= Magnetude of dipole moment, x = angle between dipole and the position vector of the point and r + magnetude of the position vector of the point.

then P = sqrt 14, cos x = 4/(sqrt 29 + sqrt 14) and r^2 = 29.

Look iam not sure of the equation or the calculation. Just an idea that might work out.
