NCERT Solution for Class 11 Maths Chapter 8 Exercise 8.2
Ex 8.2 Class 11 Maths Question-1
Find the coefficient of x5 in (x + 3)8
Ans:Find the coefficient of x5 in (x + 3)8
It is known that (r + 1)th term, (T r+1), the binomial expansion of (a + b)n is given by T r+1= aCran-rbr
Asuming that x5 occurs in the (r + 1) thterm of the expansion (x + 3)8, we obtain Tr+1 =8Cr(x)8-r3r
Comparing the indices of x 5 and Tr+1we obtain r = 3
