Hello, Im supposed to prove that the below is true(adsbygoogle = window.adsbygoogle || []).push({});

[[tex]\delta_{}im[/tex][tex]\delta_{}jn[/tex](em x en)][tex]\bullet[/tex][[tex]\delta_{}pr[/tex][tex]\delta_{}qs[/tex](er x es)] = [tex]\delta_{}ip[/tex][tex]\delta_{}jq[/tex] - [tex]\delta_{}iq[/tex][tex]\delta_{}jp[/tex]

where em, en,... are random unit vectors and that bullet point is supposed to be the dot product. Im supposed to consider all possible combinations of m,n,r, and s to show this.

Thank you
