Answer:

Explanation:
Binomial Theorem
Any power of x + y can be expanded into a sum of the form:

For any given term k, counted from 0 to n:

Note if we have to find the 7th term, we have to use k=6. The expression is:

For n=8, x=4f, y=t/3, k=6:



Calculate:

Thus:

Simplifying, the 7th term is:
