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.

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
