Question

Solution Please question of Binomial Theorem

Answer 1

Answer :

Required Coefficient = 8

Explanation :

According to the question :

In expansion of,

( 1 + x ) ( 1 + x^2 ) ( 1 + x^3 )....... ( 1 + x^100 )

x^9 can be found in the following ways :

( x^9 ) , ( x^1+8 ) , ( x^2+7 ) , ( x^3+6 ) , ( x^4+5 ) , ( x^1+2+6 ) , ( x^1+3+5 ) , ( x^2+3+4 )

or Can use Terms having ' x '

The coefficient of x^9 in each of the above 8 cases is 1 .

☃️ Therefore, Required Coefficient = 8.

❥ So, It's Done ❥ !!
