I understand that part what I dnt get is do both of my x^2 and x^3 cross out?

\[\frac{3}{\frac{x^3}{\frac{1}{x^2}}}=\frac{3}{x^3}\frac{x^2}{1}=\frac{3x^2}{x^3}=\frac{3*x*x}{x*x*x}\]

You have two x's on the top and you have three in the bottom right?

  • anonymous
yes.
anonymous
  • anonymous
Two from the top cancel two from the bottom
anonymous
  • anonymous
so you are left with zero x's on the top and one x on the bottom
anonymous
  • anonymous
understand?
anonymous
  • anonymous
so it would just be 3x
anonymous
  • anonymous
No I said there will be zero x on the top and one in the bottom of the fraction
