What is the coefficient of x²y^8 in the expansion of (x + y)^10?

 45

Step-by-step explanation:

We know that term in the binomial expansion of is given by :-

Now, term for the binomial expansion of is given by :-

 (1)

When we compare (1) to , we get m=8

Then, the coefficient of from (1) will be :-

Hence, the coefficient of is 45.
