Question
Suppose $\mathbf{A}$ and $\mathbf{B}$ are $n \times n$ matrices and $\mathbf{A}$ is nonsingular. Show that if $\mathbf{A} \mathbf{B}=\mathbf{0}$, then $\mathbf{B}=\mathbf{0}$.
Step 1
Step 1: We are given that $\mathbf{A}$ is nonsingular, which means that the inverse of $\mathbf{A}$, denoted as $\mathbf{A}^{-1}$, exists. Show more…

Inverse of a Matrix
If $\mathbf{A}$ and $\mathbf{B}$ are nonsingular $n \times n$ matrices, is $\mathbf{A}+\mathbf{B}$ necessarily nonsingular?
If $\mathbf{A}$ and $\mathbf{B}$ are nonsingular $n \times n$ matrices, use Theorem $8.6 .3$ to show that $\mathbf{A B}$ is nonsingular.
