Question: Let a = a + bi and = c + di be complex scalars and let A and B be matrices with complex entries.

Let a = a + bi and β = c + di be complex scalars and let A and B be matrices with
complex entries.
(a) Show that
a+B=a + B and aß = a B

(b) Show that the (i. j) entries of AB- and A-B- arc equal and hence that
A-B- = A-B-

a+B=a + B and a = a B
