Misalkan Matriks dari A adalah (4 -2) (3 5) dan Matriks dari B adalah (2 1) (-4 3). Nilai dari {(A-B)}^2?

NamakuDuck Diketahui matriks A = $\left[\begin{array}{ccc}4&-2\\3&5\end{array}\right]$ dan matriks B = $\left[\begin{array}{ccc}2&-1\\-4&3\end{array}\right]$
=> (A - B)²
=> $(\left[\begin{array}{ccc}4&-2\\3&5\end{array}\right]-\left[\begin{array}{ccc}2&-1\\-4&3\end{array}\right])^{2}$
=> $(\left[\begin{array}{ccc}2&-1\\7&2\end{array}\right])^{2}$
=> $(\left[\begin{array}{ccc}2&-1\\7&2\end{array}\right])(\left[\begin{array}{ccc}2&-1\\7&2\end{array}\right])$
=> $\left[\begin{array}{ccc}-3&-4\\28&-3\end{array}\right]$

Andre71 $\left[\begin{array}{ccc}4&-2\\3&5\end{array}\right] - \left[\begin{array}{ccc}2&1\\-4&3\end{array}\right] = \left[\begin{array}{ccc}2&-3\\7&2\end{array}\right]$
$\left[\begin{array}{ccc}2&-3\\7&2\end{array}\right]^{2} = \left[\begin{array}{ccc}4&9\\49&4\end{array}\right]$
