Answer 1

Answer:

a.ab-dc

this is the of this question

I may you answer is correct

Answer 2

Answer:

Given,

options.

To Find,

The correct representation of order two from the given options.

Solution,

We can simply find the answer by using some basic rules of matrices.

Considering what our 2×2 matrix looks like.

a b

c d

For the determinant, we cross multiply, and subtract them.

So, in this case, ad-bc is the determinant of the given matrix.

Hence, the correct choice is option(c). ad-bc.
