I answered the question correctly

Answer 2

Answer: The coefficient of
`x^6y^4\ term` is 210.

Explanation:

Since we have given that

`(x+y)^(10)`

We need to find the
`x^6y^4\ term`

so, we will use "Binomial rule ":

`T_(r+1)=T_6=^(10)C_(6)x^6y^4\\\\\text{So, the coefficient of }x^6y^4\ will\ be\\\\^{10C_6\\\\=(10!)/(6!* 4!)\\\\=(10* 9* 8* 7)/(4* 3* 3* 2* 1)\\\\=210`

Hence, the coefficient of
`x^6y^4\ term` is 210.
