Finding the factor by which two operators differ.

  1. Nov 27, 2012 #1
    1. The problem statement, all variables and given/known data
    I have two operators
    A^2B^2+B^2A^2

    1/2(A^B^+B^A^) 2

    By what factor do the two operators differ?


    3. The attempt at a solution
    I believe I either have to find the inner products of them and relate them somehow or use commutation?
    Not sure which one!
    I dont want help with the maths as I really need to try figure that bit out myself! But im not quite sure what the question is asking me to do.

    Shouldn't the question read "By what factor do the two operations differ"?
    That is the result of the two operations differ by only a factor, or one answer is a factor of the other.

    Thats not how the question is worded :/ Would maybe make more sense like that...But it definately says by what factor do the two operators given differ.

    That doesn't make sense. Operators are defined a certain way and give variable results when operating on the operands. So I would think they intended to write 'operations'. If that is what they realy intended why would they give two equations then?
