Use binomial theorem to expand expression 

The correct answer is: Thus, the expansion is: .

ANSWER:
Hint:
The binomial expansion is  , here  .
We are asked to find the binomial expansion of  .
Step 1 of 2:
The given expression is  . Here x = d   and value of n=4. Thus, the number of terms in
the expansion of  is 5.
Substitute the values in the binomial expansion to get the required terms. Thus, we have:



Thus, the expansion is: .
Note:
The answer can be found using the Pascal’s triangle. For an expression  , we would have n+ 1 term.
