If `[[i,0],[3,-i]]+X=[[i,2],[3,4+i]]-X,` then `X` is equal to

If x + iy=|{:(6i,-3i,1),(4,3i,-1),(20,3,i):}| , then what is x - iy equal to ?

x+iy=det[[6i,-3i,14,3i,-120,3,i]], find x and y

if I=int_(0)^(1.7)[x^(2)]dx, then I equal is

If x=a+bi is a complex number such that x^(2)=3+4i and x^(3)=2+11i, where i=sqrt(-1, then (a+b) equal to )
