If a b are two square matrices such that ab b

WebA matrix A of dimension n x n is called invertible if and only if there exists another matrix B of the same dimension, such that AB = BA = I, where I is the identity matrix of the same order. Matrix B is known as the inverse of matrix A. Inverse of matrix A is symbolically represented by A -1. WebA A and B can be any matrices B A, B are square matrices not necessarily of the same order C A, B are square matrices of the same order D Number of columns of A = number of rows of B Solution: Let A and B both have a matrices of order m×n Also, AB is defined, it means m = n. Hence, A and B are square matrices of same order.
