**[SOLVED] Similar matrices**

I was given 2 matrices and need to prove that they are similar,

after i performed row operations on it, i got

A =

[100]

[040]

[006]

and B =

[600]

[040]

[001]

I was stupid enough for not using the fact that their trace are equal to prove it. and instead, keep figuring out the invertible matrix Q that satisfies A=(Q^-1)BQ. But still, i can't figure out the matrix Q that does the work..

Can anyone tell me if there's any other way to prove the 2 matrices ar similar but do not deal with the trace? or any fast way to figure out Q?
