If `A=[(1,0,0),(0,1,0),(1,b,-10]` then `A^2` is equal is (A) unit matrix (B) null matrix (C) A (D) `-A`

If A=[(1,0,0),(0,1,0),(a,b,-1)] then A^2 is equal to (A) null matrix (B) unit matrix (C) -A (D) A

If A=[(1 ,0, 0),(0, 1,0),( a,b, -1)] , then A^2 is equal to (a) a null matrix (b) a unit matrix (c) A (d) A

The matrix A=[(-5,-8,0),(3,5,0),(1,2,-1)] is (A) idempotent matrix (B) involutory matrix (C) nilpotent matrix (D) none of these

If A=[(0,2,-3),(-2,0,-1),(3,1,0)] then A is (A) diagonal matrix (B) symmetric matix (C) skew symmetric matrix (D) none of these

Let a and b be two real numbers such that a>1,b>1. If A=([a,00,b]), then (lim_(n rarr oo)A^(-n) is (a) unit matrix (b) null matrix (c) 2I (d) non of these

If A=[(1, 0,0),(0,1,0),(a,b,-1)] and I is the unit matrix of order 3, then A^(2)+2A^(4)+4A^(6) is equal to

If matrix A=[(0,-1),(1,0)] , then A^16 =

If A=[{:(0,1),(1,0):}] then the matrix A is
