you can factor x^5 from the top. and the bottom is the difference of two squares. you can actually apply the difference of two squares formula twice. but i don't think they'd want you to mess with the denominator, since it doesn't look simpler and will end up involving radicals.

wait, when you say "etc" what do you mean? please type out the whole question. does it end with 1? something else?

you asked this in someone else's thread and it was answered. makes me wonder if that is the case with the rest of these problems.2. I have a question that has cuberoot (x + 1) * 3(cuberoot (x+1)^2)

Am I allowed to just multiply it through so that I get (x+1)^3 and then cancel the three with the cuberoot or is there some other method that I am supposed to use.

just factor from the expression.3. (similar to my first question) --> the question asks to simplify and after doing a couple things I'm stuck at:

(10x^7 - 5 + 15x^3 + 20x^5)/ x^4

I don't think this is fully simplified but I'm unsure of how to combine or factor these piece parts.

The original question was:

10x^3 - 5x^(-4) + 15x^(-1) + 20x

yes, doing that is valid. what did you end up with? i would have probably combined the fractions in the top first, but i guess it doesn't matter. you would be expected to end up with one fraction in the end anyway4. Am I allowed to split up division: for example: (2/5 + 2/4)/5 = (2/5)/5 + (2/4)/5 ??? (In the cases i tried it worked but I figured I would ask the question anyways)

Sorry for long post (I keep adding as I go) Please help!!!!!

thanks, bye
