Question

What is the coefficient of x5y5 in the expansion of (x + y)10?

Answer 1

252

GOD BLESS U. Sorry if I’m wrong I tried my best

Answer 2

C=252

Explanation:

Given:

x^5y^5

(x+y)^10

Find the coefficient of x^5y^5

To get the coefficient of x^5y^5,

we will put r = 5, in the below given general term.

The general term is : nCr =x^ry^n-r

We get:

Coefficient is = 10C5

= 10!/5!*5!

= 252

The coefficient of x^5y^5 is 252

C. 252
