Question

Can you give a clear answer to b.2? I don't need b.1 answer. Make sure the answer includes all steps

Eijklmk = dijm - dim djl
(2)
Using the summation convention, Kronecker delta, and permutation symbol, show the following well-
known vector identities: (Hint: Eq. (2) is useful to show (b.2).)
(b.1): a (bx c) = b. (cxa) = c. (axb)
(b.2): ax (bx c) = b(a c) — c(a - b)
