How can you find the column vectors $[\pmb b _ 1, \pmb b _ 2, \ldots, \pmb b _ n]$ of $B$ in the equation
\[AB = I_n\]
?
Solve $A\pmb b _ i = e _ i$ for each $i$.
\[\left(\begin{matrix} 2 \& 3 \\\\ 2 \& 2 \end{matrix}\right) B = I_n\]
How could you systematically find the column vectors $[\pmb b _ 1, \pmb b _ 2, \ldots, \pmb b _ n]$ of $B$ in the equation?
?:: Solve for $\pmb b _ i$ in
\[\left(\begin{matrix} 2 \& 3 \\\\ 2 \& 2 \end{matrix}\right) \pmb b_i = \pmb e_i\]
