Compute the product.

9 -4 5 1 0 0 -5 0 0 1 0 4 -7 6 0 0 1

Dear Student

Thank you for using Chegg !!

A	=	9	-4	5
		-5	0	-8
		4	-7	6

B	=	1	0	0
		0	1	0
		0	0	1

Clearly matrix B is an identity matrix and any matrix multiplied with an identity matrix results in itself
i.e. A.B = A

However to prove let us multiply the two matrices we get

A.B	=	9	-4	5
		-5	0	-8
		4	-7	6
