Prove that the following. [[(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

Locate the points: (1, 1), (1, 2), (1, 3), (1, 4) (2, 1), (2, 2), (2, 3), (2, 4) (1, 3), (2, 3), (3, 3), (4, 3) (1, 4), (2, 4), (3, 4), (4, 4)

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]]

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, 2, 3, 4, 5} then the relation R={(1,1), (2, 2), (3, 3), (4, 4), (1, 2), (2,3)} is

Let X = { 1,2,3,4 } and R = { (1,1), (1,2),(1,3),(2,2), (3,3),(2,1),(3,1),(1,4),(4,1)}. Then R is
