Question

What is the second term of the expand the binomial above. (8v + s)5

Answer 1

Let's assume that's a fifth power.

The first term is

`{5 \choose 0}(8v)^5 s^0`

and the second term is

`{5 \choose 1}(8v)^4 s^1`

5 choose 1 is 5 and
`8^4=2^(12)=4096.`

Answer:
`20480 v^4 s`

Answer 2

(8v + s)5 (multiply 5 into the parentheses)

(8v × 5) + (s × 5)

40v + 5s
