How do you do these questions, I have all my steps done until the last one:

2x(2x)^2: 2x(4x^2)?

Now do I multiply or add the big numbers?

also Im having trouble on these:

1. x^2(xy)^3: x2(x^3y^3)

2. 3x^2(2x)^3: 3x^2 (8x^3)

3. -2x^2y(3xy^2)^2

4. -(3x)^2: -(9x^2)?

5. 5x(2x^2)^2

6. -3x^2y(xy)^3

7. 2xy^2(3x^2y)^3

Everythinbg is done but the last step, please help, thanks
