According to the Binomial Theorem, one of the terms in the expansion of (x + y)5

? Not understanding the question.

A) 10x3y2 B) 10x5y5 C) x3y2 D) x5y5 34)

OpenStudy (anonymous):

the 34 was a mistake void 34 out please

OpenStudy (anonymous):

apply the expansion formula... (x+y)^n your ans may be (a)

OpenStudy (anonymous):

Well, you can certainly elliminate (B) and (D) nice the sum of the exponents of x and y must equal 5.

OpenStudy (anonymous):

With no additional constant outsie the binomial, the only way you will have a coefficient of 1 is on the first or last term...and those will either be x^5 or y^5. So (C) doesn't make sense either. Process of ellimination. :)

OpenStudy (anonymous):

ya....actually it can never be 10x^5...ar even x^5y^5 and the term x^3y^2 as it came in middle it must have some coefficient...thats not there ...so you don't even need expansion formula
