e11, e12, e21, and e22 are 2x2 matrices with all zeros except for a one in ij=11, ij =12, ij=21, and ij=22, respectively.(adsbygoogle = window.adsbygoogle || []).push({});

I know how to show if vectors are a spanning set but I don't know what to do about matrices.

Can someone show me how to approach this? Thanks.
