If A is an n Times n matrix explain how to find the followin

If A is an n Times n matrix, explain how to find the following. The minor M_ij of the entry a_ij. Take the determinant of the (n - 1) Times (n - 1) matrix that is left after deleting the ith row and ith column. Take the determinant of the (n - 1) Times (n - 1) matrix that is left after deleting the ith row and jth column. Take the determinant of the (n - 1) Times (n - 1) matrix that is left after deleting the jth row and jth column. Take the determinant of the n Times n matrix that is left after deleting the ith row and jth column. Take the determinant of the n Times n matrix. The cofactor C_ij of the entry a_ij. If i + j is odd, then C_ij = M_ij. If i + j is even, then C_ij = -M_ij. If i + j is odd, then C_ij = -M_ij. If i + j is even, then C_ij = M_ij. If i + j is negative, then C_ij = -M_ij. If i + j is positive, then C_ij = M_ij. C_ij = M_ij C_ij = -M_ij The determinant of A. |A| = a_11C_11 + a_12C_12 + ... +a_1nC_1n |A| = a_11C_11 - a_12C_12 - ... -a_1nC_1n |A| = a_11C_11 - a_12C_12 + ... -a_1nC_1n |A| = a_11C_11 + a_22C_22 + ... +a_nnC_nn |A| = a_11C_12 + a_12C_11 + ... +a_1nC_1n
