Question

Suppose that A, B, and C are invertible matrices of the same

Answer 1

Answer:

Step-by-step explanation:

Given that t A, B, and C are invertible matrices of the same

size.

To pr that $(ABC)^{-1} = C^{-1}B^{-1}A^{-1}.$

to pr that  $( ABC) (C^{-1}B^{-1}A^{-1})=e$

LS=$( AB(C (C^{-1})B^{-1}A^{-1})\\=ABIB^{-1}A^{-1})\\=A(BB^{-1})A^{-1})\\=AA^{-1})\\=I$

Thus proved
