Question

find the value of deteraminant [ 5 6 ]
[ 7 8 ]​

Answer 1

Step-by-step explanation:

Find the value of the following determinants. 5 & 3 - 7 & 0

Answer 2

Given that, [5 6] [7 8]

We can also write it as,

$\left[\begin{array}{ccc}5&6\\7&8\end{array}\right]$

Now after solving we get,

$D=|5*8-7*6|\\D=|40-42|\\D=|2|$

So, the value of determinant for the given values is $D=|2|$
