If `A={0,1,2,3,4,5}`, then `n(A)` is ....

If ={1.2.3.4,5,...,101,A={1,2,3,4,5}.A delta B={1,2,3,4), then n(B-A) is

If A=[(1, 2, 0 ),(3,-4, 5),( 0,-1, 3)] , compute A^2-4A+3I_3 .

If two digit number are formed using the digits 0, 1, 2, 3, 4, 5 with repeating them, then n(S) =

Given that M=[(3,-2),(-4,0)] and N=[(-2,2),(5,0)] then M+N is a

If A=[(-1,0,2),(3,1,4)], B=[(0,-2,5),(1,-3,1)] and C=[(1,-5,2),(6,0,-4)], then find (2A-3B+4C).

If A=[[1,2,3]], B=[(-5,4,0),(0,2,-1),(1,-3,2)] then (A) AB=[(-2),(-1),(4)] (B) AB=[-2,-1,4] (C) AB=[4,-1,2] (D) AB=[(-5,4,0),(0,4,-2),(3,-9,6)]
