(n^-2/2m^2)^-2 =(2m^2/n^-2)^2 =4m^4/n^-4 =(4m^4)n^4 (a) is your answer N.B. x^-n = 1/x^n.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
