Question
What number does C3 represent in the expansion 
? Explain.
The correct answer is: = 4
ANSWER:
Hint:
The binomial expansion is , 
.
The value of 
We are asked to find what number does 
represent in the expansion .
Step 1 of 2:
The expansion is:
Here, represents the coefficient of in the expansion.
Step 2 of 2:
The value of n=4, so the value of is:
= 4
Note:
The value is called the combination permutation.
