Find the determinant of the following matrix. [5. -4] [8 2]

determinant formula looks like  ad - bc in a 2 x2 matrix when it's in the from of

a b

c d

as the one is here

Step-by-step explanation:

5*2 - (-4*8)

=10 - (-32)

=10 + 32

= 42

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
