Question

What is the seventh term of (x + 4)^8

Answer 1

(a + b)^n = sum(k=0 to n) C(n, k) * a^(n - k) * b^k.
So we have:
(x + 4)^8 = sum(k=0 to 8) C(8, k) * x^(8 - k) * 4^k.
Then, we see that the seventh term will occur at k = 6.
Therefore, the seventh term is C(8, 7) * x^(8 - 7) * 4^6 = 32768x^2.
