Answer 2

[ 4 2 ] x [ -2 5 7 -1 ]​ = [- 10,836]

Explanation:

Here, the given expression is:

[ 4 2 ] x [ -2 5 7 -1 ]​

Now solving : [ -2 5 7 -1 ]​ , we get

[ -2 5 7 -1 ]​ = [-258]

Now simplifying

[-258] x [ 4 2 ] = - 10,836

⇒ [ 4 2 ] x [ -2 5 7 -1 ]​ = [- 10,836]

Hence the solution is: [- 10,836]
