If 𝐴 = [−2 43 −1] 𝑎𝑛𝑑 𝐵 = [1 34 −1], then verify that either B is a multiplicative inverse ofA or not?

To verify if B is a multiplicative inverse of A, we need to multiply matrix A by matrix B. If the result is an identity matrix, then B is a multiplicative inverse of A.

However, in this case, A and B are not square matrices, they are 1x3 matrices. The concept of multiplicative inverse is not defined for non-square matrices.

Therefore, we cannot verify if B is a multiplicative inverse of A because the concept does not apply to these matrices.
