Homework Statement
(1+n)^n≥ 5/2* n^n- 1/2* n^(n-1) for n≥2
Homework Equations
i know I have to use this formula
(1+x)^n=1+nx/1!+(n(n-1) x^2)/2!+⋯
The Attempt at a Solution
And you take x=n from my original inequality but after that I have no clue
(1+n)^n=1+n/1! n+(n(n-1) n^2)/2!+⋯
but it seems very complicated !
