Hermitian problem I need some help

  1. Mar 2, 2010 #1
    1. The problem statement, all variables and given/known data

    Prove that if A and B are hermitian, so is (A+B)^n

    2. Relevant equations

    if an operator is hermitian then it is equal to its conjugate (A= A+)

    3. The attempt at a solution

    im pretty much bad when it comes to math, any hints would be appreciated ..
    thanks in advance..

    What else do you know about hermitian matrices? For example, is the sum of two hermitian matrices hermitian? What about their product?
