I am writing answer in English so all users can easily understand :
We have the Vector : r:3i+ 2j

Magnitude of this vector :
 |r| = \sqrt{ {2}^{2} + {3}^{2} } = \sqrt{13}

Unit vector is given by :
u = \frac{r}{ |r| } = \frac{3i + 2j}{ \sqrt{13} } = \frac{3}{ \sqrt{13} } i + \frac{2}{ \sqrt{13} } j
Therefore, u is required unit vector.
