Let ${\displaystyle {}K}$ be a field, and let ${\displaystyle {}V}$ be a ${\displaystyle {}K}$-vector space of dimension ${\displaystyle {}n}$. Let ${\displaystyle {}{\mathfrak {u}}=u_{1},\ldots ,u_{n},\,{\mathfrak {v}}=v_{1},\ldots ,v_{n},}$ and ${\displaystyle {}{\mathfrak {w}}=w_{1},\ldots ,w_{n}}$ denote bases of ${\displaystyle {}V}$. Show that the transformation matrices fulfill the relation

${\displaystyle {}M_{\mathfrak {w}}^{\mathfrak {u}}=M_{\mathfrak {w}}^{\mathfrak {v}}\circ M_{\mathfrak {v}}^{\mathfrak {u}}\,.}$
