If the equation Ax= 0 has only the trivial solution, then A is row equivalent to the nxn identity matrix. A. False; by the Invertible Matrix Theorem if the equation Ax = 0 has only the trivial solution, then the matrix is not invertible; this means the columns of A do not span Rn. Thus, A must also be row equivalent to the nxn identity matrix. В. True; by the Invertible Matrix Theorem if equation Ax = has only the trivial solution, then the equation Ax= b has no solutions for each b in Rn. Thus, A must also be row equivalent to the nxn identity matrix. С. False; by the Invertible Matrix Theorem if the equation Ax= 0 has only the trivial solution, then the matrix is not invertible. Thus, A cannot be row equivalent to the nxn identity matrix. D. True; by the Invertible Matrix Theorem if the equation Ax = 0 has only the trivial solution, then the matrix is invertible. Thus, A must also be row equivalent to
