WebOct 6, 2024 · Use the formula to find the inverse of matrix A. Verify your answer by augmenting with the identity matrix. A = [1 − 1 2 3] Answer Example 7.8.5: Finding the … WebThus. ( A B) − 1 = B − 1 A − 1. Note that the matrix multiplication is not commutative, i.e, you'll not always have: A B = B A. Now, say the matrix A has the inverse A − 1 (i.e A ⋅ A − 1 = A − 1 ⋅ A = I ); and B − 1 is the inverse of B (i.e B ⋅ B − 1 = B − 1 ⋅ B = I ). land and registry uk
