fiNd the Coefficient Of $$x ^ { 8 }$$ In the Power Series of Each of the Function

Short Answer

find the coefficient of $$x ^ { 8 }$$ in the power series of each of the function.
- $$( 1 + x ) \left( 1 + x ^ { 2 } \right) \left( 1 + x ^ { 3 } \right) \left( 1 + x ^ { 4 } \right) \left( 1 + x ^ { 5 } \right)$$
