`|[(a+1)(a+2), a+2, 1], [(a+2)(a+3), a+3, 1], [(a+3)(a+4), a+4, 1]| =-2`

Find value of determinant of A =abs[[(a+1)(a+2),(a+2),1],[(a+3)(a+2),(a+3),1],[(a+3)(a+4),(a+4),1]]

The value of |((a+1)(a+2),a+2,1),((a+2)(a+3),a+3,1),((a+3)(a+4),a+4,1)| is

Using properties of determinants,prove that ([(a+1)(a+2),a+2,1(a+2)(a+3),a+3,1(a+3)(a+4),a+4,1]|=-2

If A=[[1, 2, 3], [1, 3, 4], [3, 4, 3]] , then |A^(-1)|=

If A = [(2,2,1), (1,3,1), (1,2,2)] then A^-1+(A-5I) (AI)^2 = (i) 1/ 5 [[4,2, -1], [-1,3,1], [-1,2,4]] (ii) 1/5 [[4, -2, -1], [-1, 3, -1], [-1, -2,4]] (iii) 1/3 [[4,2, -1], [-1,3,1], [-1,2,4]] (iv) 1/3 [[4, -2, -1], [-1,3, -1], [-1, -2,4]]

Let R = {(1, 3), (4, 2), (2, 4), (2, 3), (3, 1)} be a relation on the set A = {1, 2, 3, 4}. The relation R is

Let R = {(1, 3), (4, 2), (2, 4), (2, 3), (3, 1)} be a relation on the set A = {1, 2, 3, 4}. The relation R is

A = {1, 2, 3, 4} and R = {(1, 1), (1,3), (2, 2), (3, 1),(3, 4),(3,3),(4, 3), (4,4) } is a relation on A xx A , then which one of the following is correct?

If A=[[1, -1, 2], [0, 2, -3], [3, -2, 4]] , then |A^(-1)|=
