This question was on one of my practice tests for my ACT. I didn't understand it at all as soon as I read it. So, could you please answer the question and explain to me how it all works? Thank you very much.

-4x(6x^4) How do I simplify this? I have several choices, and the one I'm thinking is -24x^4. Is that correct? I need an explanation. Thanks!!

Also, when I see (4x)^2, does that mean to square the 4 and get 16x^2 or just multiply and get 4x^2?

When (y/-3)^2 is simplified, does it become y^2/9? (The / means fraction.)

Thanks!!
