If ` [(1,2,a),(0,1,4),(0,0,1)]^n=[(1,18,2007),(0,1,36),(0,0,1)]` then find the value of `(n + a).`

if [{:(1,2,a),(0,1,4),(0,0,1):}]=[{:(1,18,2007),(0,1,36),(0,0,1):}] then find the value of n

If A={:[(1,2,x),(0,1,0),(0,0,1)]:}, B={:[(1,-2,y),(0,1,0),(0,0,1)]:} and AB=I_(3) , then find the value of x + y + 1.

If A=[(1,1,0),(0,1,1),(0,0,1)] and ninN then A^(n)=

If [2 1 3] [{:(-1,0,-1),(-1,1,0),(0,1,1):}][{:(1),(0),(-1):}] =A, then find the value of A.

If [2 1 3] [{:(-1,0,-1),(-1,1,0),(0,1,1):}][{:(1),(0),(-1):}] =A, then find the value of A.

If [(0, 1), (-1,0)]^n = [(1,0),(0, 1)] then the value of n is

If [{:(2,1,3):}][{:(-1,0,-1),(-1,1,0),(0,1,1):}][{:(1),(0),(-1):}]=A , then find the value of A .

If A=[(1,0,0),(0,1,0),(3,4,-1)] and A^(n)=l , then value of n is equal to

If [(1,0,0),(2,0,1),(1,0,2):}][(0),(2),(x):}] = 0 find the value of x.
