Given A=[−32−117]\displaystyle {A}={\left[\begin{array}{cc} -{3}&{2}\\-{11}&{7}\end{array}\right]}A=[−3−1127] and B=[7−211−3]\displaystyle {B}={\left[\begin{array}{cc} {7}&-{2}\\{11}&-{3}\end{array}\right]}B=[711−2−3] , 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?
