By definition we have that the binomial expansion theorem is given by:
(see attached image)
From here, we must replace the values of k and n correctly.
We have a binomial of the form:
Therefore, the value of n is given by:
We have the following term:
Therefore, the value of k is given by:
Substituting values and calculating (see attached image), we have that the value of the coefficient is given by:
Thus,
Answer:
The value of the coefficient for the term x^7y is 8.
