Question

Given A = `[(0, 4, 6),(3, 0, -1)]` and B = `[(0, 1),(-1, 2),(-5, -6)]`, find if possible A²

Given A = `[(0, 4, 6),(3, 0, -1)]` and B = `[(0, 1),(-1, 2),(-5, -6)]`, is the following possible A²

Answer 1

Product AA (=A²) is not possible as the number of columns of matrix A is not equal to its number of rows.
