My first and naive impression is that the result is 0 but according to Salinas, Introduction to Statistical Physics that's $3x^{1/2}y O(x/y)^3$ I think Taylor expansion would do it The thingNow, we have the coefficients of the first five terms By the binomial formula, when the number of terms is even, then coefficients of each two terms that are at The Binomial Theorem is the method of expanding an expression which has been raised to any finite power A binomial Theorem is a powerful tool of expansion, which has application in Algebra, probability, etc Binomial Expression A binomial expression is an algebraic expression which contains two dissimilar terms Ex a b, a 3 b 3, etc

Why create a profile on Shaalaacom? We are technically FOILing this out with a power of 3 (xy)(xy)(xy) So we can first factor out the first two "xy"s, multiplied by the last "xy" Coefficients are the number that comes in front of a variable In this case, 1 comes in front of , 3 comes in front of , 3 comes in front of , and 1 comes in front of Thus 1, 3, 3, 1If we examine some simple binomial expansions, we can find patterns that will lead us to a shortcut for finding more complicated binomial expansions
