The preceding exercise tells us that the inverse of an elementary matrix is also elementary matrix of the same type. Use this fact to write A as a product of elementary matrices if [120] [100] [100] [001] A-¹ 0 1 0 020 3 1 0 01 0 0 1 001 0 0 1 1 0 (Do not compute for A-¹ explicitly, use the fact that (EF)-¹ = ....)
