What is the coefficient of the x6y4 term in the expansion of (x+y)10?
|dw:1354008992851:dw| the coefficient of x^6y^4 is 210
We can find this by binomial expansion Expansion of (a+b)^n \[\Large (a+b)^n=^nC_0 a^n b^0+^nC_1 a^{n-1}b^1+^nC_2 a^{n-2}b^2.....^nC_n a^{0}b^n\] @Arijit2012 Do you understand this formula?
