Expand  using binomial theorem.

The correct answer is: Thus, the expansion is:

ANSWER:
Hint:
The binomial expansion is  , here  .
We are asked to find the binomial expansion of  using binomial theorem.
Step 1 of 2:
The given expression is  . . The value of n=3. Thus, the number of terms would be n+1=3+1=4.
Step 2 of 2:
Substitute the values in the expression to get the terms of the binomial expansion;



Thus, the expansion is:
Note:
The answer can be found using the Pascal’s triangle. For  , we would consider the (n+1) th row as the coefficients.
