Given A=[−130−1]\displaystyle {A}={\left[\begin{array}{cc} -{1}&{3}\\{0}&-{1}\end{array}\right]}A=[−103−1] and B=[−1−30−1]\displaystyle {B}={\left[\begin{array}{cc} -{1}&-{3}\\{0}&-{1}\end{array}\right]}B=[−10−3−1] , determine whether A\displaystyle {A}A and B\displaystyle {B}B are inverses.
AB=\displaystyle {A}{B}=AB=
BA=\displaystyle {B}{A}=BA=
Are A\displaystyle {A}A and B\displaystyle {B}B inverses?
