What is the product? [ 4 2 ] x [ - 2 5 7 - 1 ]

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

Step-by-step 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]
