If A = [(2, -2),(-3,1)] , then show that ( A + I) ( A - 4 I) = O

Simplify (i) (1 + i)^(18) " " (ii) (-sqrt(3) + 3i)^(31)

Find the octant in which the following points lie (i) (-3,1,-2) (ii) (3,1,-2) (iii) (-3,1,-2) (iv) (-3,-1,-2)

If A = [(-1,2),(3,1)],B=[(1,0),(-1,0)] then the value of 2A+B+2I=

Verify : A(adj.A)=(adj.A)A=|A|I when : A=[{:(2,1,5),(3,-2,-4),(-3,1,-2):}]

If A={:((-2,-1),(-5,-3)):}B={:((-3,1),(5,-2)):}and(AB)^(n)=I then n is (a/an)

If {:A=[(3,1),(-1,2)]:}," then "A^(-2)=

If {:A=[(5,2),(3,1)]:}," then "A^(-1)=

If {:A=[(5,2),(3,1)]:}," then "A^(-1)=
