Choose correct alternative for the question.Find the value of | 5 3|
(A)-1 : : : : : : : | -7 4|
(B) -41
(C) 41
(D) 1

Answer 1

Here question is incorrect.
Correct QUESTION is in the attachment .

DETERMINANT :
|a b |
|c d |
is a determinant. (a, b), (c, d) are rows and , | a| ,|b |
                                                                       |c | , |d |are columns.
There are 2 elements in each column and 2 elements in each row so the Degree of this determinant is 2. It represents a number which is (ad-bc). ad-bc is the value of determinant |a b |
                    |c d |

SOLUTION :
Option D is Correct : 1

Given :
a = 5 , b= 3 , c = -7, d = - 4
The value of determinant = ad - bc
= 5×-4 - 3 × -7
= -20 +21 = 1
= 1
Hence , the value is 1 .
