 P: 56 (1+x)^n=1+nx/1!+(n(n-1) x^2)/2!+⋯+ what are the last few terms of this ? I looked and tried but don't seem to get any text book answer for this.
 Sci Advisor HW Helper Thanks P: 26,148 hi rohan03! (try using the X2 and X2 buttons just above the Reply box ) the binomial coefficients are symmetric (nCr = nCn-r), so it ends … + n(n-1) xn-2/2! + nxn-1/1! + xn
 P: 56 Thank you . Can I prove with the help of this : (1+n)n ≥ 5/2nn- 1/2n n-1
 P: 56 Binomial theprem and expansion and if yes - please guide on how
