Question

What is the determinant of this matrix:

Answer 1

$\\ \rm\Rrightarrow \left|\begin{array}{ccc}0 &8 \\ 7& 0\end{array}\right|$

$\\ \rm\Rrightarrow 0-8(7)$

$\\ \rm\Rrightarrow 0-56$

$\\ \rm\Rrightarrow -56$

Answer 2

Answer:

-56

Step-by-step explanation:

Formula to get determinant is::

$\left[\begin{array}{ccc}a&b\\c&d\end{array}\right] = ad-bc$

0(0)-8(7)

0 - 56

-56
