The tThe term 10x3y2 is a term in which binomial expansion?

(x + y) 5

(x + y) 6

(5x + 2y) 6

(x + y) 8

(x + y) ^5.

Step-by-step explanation:

The (r+1) th term of (x + y) ^n = nCr x^n-r y^r

Compare this with 10x^3 y^2 we get

nCr = 10, n-r = 3 and r = 2 giving n = 3+2 = 5

5C2 = 10.

So the answer is (x + y) ^5.
