WebMar 5, 2024 · To begin with, since each elementary row operation has an inverse, M = E − 1 1 E − 1 2 ⋯. while the inverse of M is. M − 1 = ⋯E2E1. This is symbolically verified as. M − 1M = ⋯E2E1E − 1 1 E − 1 2 ⋯ = ⋯E2E − 1 2 ⋯ = ⋯ = I. Thus, if M is invertible then M and can be expressed as the product of EROs.
