Hi guys,
I have to prove the following in-equality (the one at the top, beneath it is given in the question):
This is what I've done so far:
And this is what I want to prove next, but I don't know how to prove the step I marked with the red underline (I don't even know if it's true but it seems to me the way to prove the question):
Any help will be much appreciated!
