Please any math helper!!
posted by Sophie .
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
Everything is done but the last step, please help, thanks

If no math tutor comes online who can help you, you should see if you can find explanations here:
http://www.khanacademy.org/
There is no need to connect with Facebook or anything. Just scroll down to the Math section (just under BROWSE OUR LIBRARY) and find the math level you're studying. Once you're in the right section, go through the videos in which different math concepts are taught.
Make sure you don't just sit around here waiting for someone to show up!! 
Here are other websites that may have explanations to help:

Not sure what it is you want to do. What is the "last step"? The "big numbers" are just coefficients, and can be moved around as needed, since multiplication is commutative.
x^2(xy)^3: x2(x^3y^3): x^5y^3
3x^2(2x)^3: 3x^2 (8x^3): 3x^2 * 8x^3: 24x^5
2x^2y(3xy^2)^2: (2)(x^2y)(9)(x^2y^4): 18x^4y^5
(3x)^2: (9x^2): (1)(9x^2): (1)(9)x^2: 9x^2
5x(2x^2)^2: (5)(x)(4x^4): 20x^5
3x^2y(xy)^3: 3x^5y^4
2xy^2(3x^2y)^3: 54x^7y^5
One thing they didn't test was things like
(3xy^2)^2: (3)^2 x^2y^4: 9x^2y^4
having a "" inside the parens can make a difference!
