How do I distribute it?

Answer 3

\[4c^2(5c^4-3)=(4c^3)(5c^4)-(4c^3)(3)\]

Answer 4

*2

Answer 5

\[a^x(a^y)=a^{x+y}\]
\[(a^x)^y=a^{x*y}\]

Answer 6

Alright. So, when I multiply (4c^2) (5c^4) the power because 6? And do I just multiply 4 by 3 or all of it? Sorry, I just got back to school and I'm lost.

Answer 8

Yes, you are correct

Answer 9

Is it 20c^6-12c^2?

Answer 10

Yup, that's all you have to do

Answer 11

Sweet!
Thanks

Answer 12

Yup!

Answer 13

Wait. Do you have to subtract the two after that or is it done?

Answer 14

Well the equation you have is like: x^3-x, tell me, can you subtract those?

Answer 15

I don't think so because the power makes it different than the other x so we don't know what it is to subtract, right?

Answer 16

yup, so you have to leave it as it is.
