(i) 
(ii) 
(iii) 
+ 
.
(iv) 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(i) 0 (ii) 0 (iii) 0 (iv) 
Sol. (i) 
Applying C 2 → 2C 2 + C 3
In this two rows are similar so |A| = 0
(ii) 
It is skew-symmetric determinant of odd order so |A| = 0
(iii) 
+ 
Applying operation in first determinant
C 1 
C 2
+ 
Applying operation in first determinant
C 2 
C 3
= 
+ 
Applying operation in first determinant
R 1 
R 3
– 
+ 
= 0
(iv) 
= 
= 
C 1 → C 1 − C 2
= 
=
