Question

for the expansion of (x+4)^8, find the 6th term.

Answer 1

\[\dbinom{8}{5}x^34^5\]

Answer 2

exponents must add to 8
\(\dbinom{8}{5}\) read "eight choose five" compute via
compute \(\dbinom{8}{5}\) via \(\frac{8\times 7\times 6}{3\times 2}\)
cancel first multiply last

Answer 3

okay so 56^3 (56 from the 8x7x6/3x2) and 4^5 multiply together for answer?

Answer 4

no nevermind that's wrong :/
