Question

Matrices (comments for picture).

Answer 1

Do they want me to multiply AB and find it's inverse?

Answer 2

I'd think not, looks like find first A and then B, and then multiply them both, then find the inverse of that product matrix

Answer 3

Hey, I figured it out and seems we were both wrong. There is a rule that states:
(AB)^-1 = 8^-1(A^-1). We just multiply the two inverse matrices first B then A.

Answer 4

(AB)^-1 = B^-1(A^-1)*
