If A[[1,-3],[1,4]]=[[7,0],[0,7]] then A is :

Is [(0,1,4),(-1,0,7),(-4,-7,0)] symmetric or shew symmetric?

If A=[[-1,0],[4,2],[0,-1]] then find (-7) A.

If A= [[7,2],[-1,4]] and I= [[1,0],[0,1]] show that (A-5I) (A-6I)=0

If |[x,0],[7,1]|=|[3,0],[7,1]| then x=

Is A=[{:(0,1,4),(-1,0,7),(-4,-7,0):}] symmetric or skew symmetric?
