If `A=[{:(i,-i),(-i, i):}]` and `B=[{:(1,-1),(-1,1):}]`, then `A^(4)` equals to-

If A=[[i,-i],[-i, i ]] and B=[[1,-1],[-1,1]] ,then A^( 8 ) equals,(where i=sqrt(-1) ) 4B 128 B -128 B -64 B

If A+I=[(3,-2),(4,1)] then (A+I)(A-I) is equal to

If P=[(i,0,-i),(0,-i,i),(-i,i,0)] and Q=[(-i,i),(0,0),(i,-i)] then PQ is equal to (A) [(-2,2),(1,-1),(1,-1)] (B) [(2,-2),(-1,-1),(-1,1)] (C) [(2,2),(-1,1)] (D) [(1,0,0),(0,1,0),(0,0,1)]

If A=[{:(4i-6,10i),(14i,6+4i):}]and k(1)/(ki), where i- sqrt(-1), then kA is equal to

If A=[{:(4i-6,10i),(14i,6+4i):}] and K=(1)/(2i), where i= sqrt(-1) . Then kA is equal to :

If A=([i,-i],[-i,i]) , B=([1,-1],[-1,1]) , A^(8)=KB and K=a^(b) then a+b=
