Show that if A and B are matrices which don’t commute, then e A + B ≠ e A e B , but if they do commute then the relation holds. Hint: Write out several terms of the infinite series for e A , e B , and e A + B and do the multiplications carefully assuming that A and B don’t commute. Then see what happens if they do commute.
