Suppose A has both a left inverse L and a right inverse R. Find the following. LA= = AR Remember matrix multiplication is associative, so LAR could be two different matrices, depending on how you group the factors. L(AR)= (LA)R = Prove: If A has a left inverse L and a right inverse R, then L = R. Given a matrix M, a left inverse is a matrix L where LM size. Suppose M is a 2 x 4 matrix. I, the identity matrix of the appropriate Explain why M is unlikely to have a left inverse. Suggestion: What problems might you encounter when trying to find a left inverse of a 2 x 4 matrix. Why might no solution exist? (This question will be graded after the assignment due date)
