I just started my first college calc class, and I cannot remember anything from Algebra....
What I need to know right now is.....
So I have (81x^-4 * y^8)^-1/4 * (xy^1/4)
All I need to do is simplify.
This is what I went to.
((x^4/81y^8))^1/4 * (xy^1/4)
I'm not sure if this is right so far. If it is, I don't know what to do next. I was thinking that I could distribute the fourth root to each thing inside the parentheses (if I can do that??) so it would be (x/3y^2) * (xy^1/4)
Anyway, that's all I really need to know right now.
Your help is appreciated, thanks!
