 P: 14 The equation you need here is $$E = \frac{kq}{r^2} * \hat{r}$$, where k is the permitivity of free space. $$\hat{r}$$ represents the radial unit vector from the point charge to the point where you are calculating the electric field, and shouldn't have a magnitude. (I think your * < x,y,z> is indicating that you're multiplying by a magnitude, which would be incorrect). Also, since this is a vector field, use their coordinate system and stay consistent.
