I'm trying to work out the following, but have gotten myself a bit confused I'm still getting to grips with using indices:
if I have $$\bar{\nabla} \times (\bar{a}\bar{x})\bar{b}$$
I re wrote this as: $$\epsilon_{ijk}\partial_j(a_ix_j)b_k$$
But I don't really know what to do now to expand/simplify it? Any guidance would be much appreciated.
