Which of the following terms appear in the expansion of (x+y)^8? the letter a in each term represents a real constant. a. ay^4 b. ax^4y^4 c. ax^4 d. ax^3y^5? the correct answer is d. b.

The given expression is

The exponent of x is decreasing and y in increasing .

That is ,

Where a,b,c,d,e,f,g,h,i are th constants

So the correct options are b and d .

c

-by-step explanation:

it would be c
