what is the second term of (x+y)^4?
To find the second term of (x+y)^4, we can use the binomial theorem, which states that the coefficients of the terms in the expansion are given by the combination formula.
The binomial expansion of (x+y)^4 is:
(x+y)^4 = 1*(x^4)*(y^0) + 4*(x^3)*(y^1) + 6*(x^2)*(y^2) + 4*(x^1)*(y^3) + 1*(x^0)*(y^4)
The second term in this expansion is 4*(x^3)*(y^1).
Therefore, the second term of (x+y)^4 is 4*(x^3)*(y^1).
