(3*sqrt(2) - 4)^2 (x^2 - x) / (x^2 - 1) divided by (x^2 - 2x) / ( x^2 + 3x + 2) 2x^-1y^2z^3)^-3(3x^2y^-3z^-4)^2 answer should contain only positive exponents I really have no idea where to even start there. We had this big ole thing to do and these three are the only ones I'm clueless on. Seeing how I already failed the class once, I'm a bit desperate here. I look at these and go So some help would REALLY be appreciated. Help a fellow Mac-head out.
