Please help me on this...!
Let A and B be n x n matrices and let C = AB. Prove that if B is singular then C must be singular.
(The hint they provided is to use this theorem : Equivalent conditions for nonsingularity. 1. A is singular. 2. A x=0 has only the trivial soultion 0. 3. A is row equivalent to I )
Please please help!
