-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!!

You are multiplying the numbers and the x's. Wich means you multiply the coefficients and add the powers of the x's.
-4x(6x^4) = -24x^5
(4x)^2 = (4x)(4x) = 16x^2
(y/-3)^2 = (y/-3)(y/-3) = ( y^2)/9

Multiply -4*6*x*x^4 = -24 x^5
16x^2 [Each term inside the paretheses gets squared)
Yes. Both numerator and denominator get squared

1. -24x^5 (don't forget to multiply the x too)
2.16x^2
3.yes
