state whether or not a constant will appear in the expansion of (x+y)^11
what does this mean? please help
in the expansion of
(x+y)^11 we get
x^11 + 11x^10y + 55x^9y^2 + ... + 11xy^10 + y^11
each term will have some combination of x and y so that the exponents add up to 11
A constant would have no variables, which cannot happen in the above question.
