What is the 9th term of the expansion (x+y)^35 ?

Question

Binomial theorem formula

step by step solution please :)

Answer 1

kth term of a binomial expansion. r = k - 1. C(n,r) x^(n-r)y^r, where CC(n,r) is number of combinations of n taken r at a time

here n = 35 and r = 9 - 1 = 8, so

9th term is C(35,8)x^27y^8
