I would like to take divergence of the following expression(adsbygoogle = window.adsbygoogle || []).push({});

∇.((xi × xj × xk)/r^3), which is a triadic.

here × denote a dyadic product and r=mod(r vector) and xi, xj and xk are the components of r vector. So, the above eq. can also be written as

∇.((xixjxk ei×ej×ek)/r^3), where ei, ej and ek are unit vectors in i, j and kth directions.

I know how to take divergence of a dyadic. I guess that we can write the triadic as a product of dyadic and vector and then proceed. I am looking for the exact expression of the divergence of dyadic product of a dyadic and a vector.

I would appreciate any help.
