Answer 1

Question :

Find the value of given determinant .

Theory :

Determinant : Every square matrix associats to an expression or a number which is known as it's determimat.

⇒If $A=(a_{ij})$ is a square matrix of order n then determimat of A is denoted by |A|

• Value of determinant of order 2

⇒Value of a determinat of order 2 is equal to product of the principal diagonals element minus product of the preceding diagonals elements

Solution :

Given determinant order = 2

let the given determinant be A

|A| = $\dfrac{-4}{3}$
