Answer 1

Are you familiar with Pascal's Triangle and the Binomial Theorem?
What about the combinations formula?

Answer 2

I know about Pascal's Triangle

Answer 3

That's a good start. It'll give you the binomial coefficients.
The binomial (5v+s) to the 5th power will be a 6 term polynomial.
From the 5th row of Pascal's Triangle, you see the binomial coefficients:
1 5 10 10 5 1.

Answer 4

The exponents on (5v) start at 5 and go down to 0. The exponents on (s) start at 0 and go up to 5, as the terms progress.

So the first term will be \((1)(5v)^5(s)^0\)

And the second term will be \((5)(5v)^4(s)^1\)

Understand how I got those?

Answer 5

Was it by the Binomial Theorem? I learned a little about it yesterday, but I don't remember all of it.

Answer 6

Yes, binomial theorem.

Answer 7

Looking at those answer choices.. are you sure it's not actually looking for the second-to-the-last term?

Answer 8

It didn't specify, but I think it could be. Is it only one of the answers if you look at the second-to last term?

Answer 9

Yes, I see the 2nd-to-last term in that list.

Answer 10

Is it 24s^4v?

Answer 11

That is very close.

Answer 12

Is it just 25s^4?

Answer 13

\(25s^4v\)

Answer 14

(you said 24 . . .)

Answer 15

Oops XD
Thank you for helping me

Answer 16

Binomial theorem is really easy once you get the pattern.
