Verification of the productU.del (R)=U

Vectors are written in bold

2. Relevant equations

R=ix +jy +kz

3. The attempt at a solution

I cannot understand what is going on. If del R is the gradient vector of R, then the problem will be scalar product, whose answer is Ux + Uy + Uz, not a vector as it is written on the book. And if del R is the scalar product of del and R, then the answer is going to be a vector, but it will be 3Unot onlyU.
