|[2+3i,4],[1,2-3i]|

If A=[[1,2-3i,3+4i],[2+3i,0,4-5i],[3-4i,4+5i,2]] ,then A is (A) symmetric (B) Skew - symmetric (C) hermitian (D) Skew - hermitian

If A=[[2,-1],[-1,2]] ,show that A^2-4A+3I=0 .

If A=[(1,2-3i,3+4i),(2+3i,0,4-5i),(3-4i,4+5i,2)] then A is

If A=[(1,2-3i,3+4i),(2+3i,0,4-5i),(3-4i,4+5i,2)] , then show that A is hermitian matrix.

A=[(1+i,2-3i,4),(7+2i,-i,3-2i)] then the conjugate of A is

A=[(1+i,2-3i,4),(7+2i,-i,3-2i)] , find the conjugate of A.

If A= [[5,2],[-1,2]] and I= [[1,0],[0,1]] show that (A-3I) (A-4I)=0

Evaluate the following: [(1+i, 0), (2,2-3i)] - [(i, -1),(3+i , 2 i)]
