dividing by 1/x^2 is the same as mutiply the numerator by x^2

Wait that is wrong.

5. anonymous

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

6. anonymous

$\frac{3}{\frac{x^3}{\frac{1}{x^2}}}=\frac{3}{x^3}\frac{x^2}{1}=\frac{3x^2}{x^3}=\frac{3*x*x}{x*x*x}$

7. anonymous

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

8. anonymous

yes.

9. anonymous

Two from the top cancel two from the bottom

10. anonymous

so you are left with zero x's on the top and one x on the bottom

11. anonymous

understand?

12. anonymous

so it would just be 3x

13. anonymous

No I said there will be zero x on the top and one in the bottom of the fraction

14. anonymous

3/x

15. anonymous

$\frac{3*x*x}{x*x*x}=\frac{3}{x}$

16. anonymous

yes you are correct good job

17. anonymous

okay thank you. :) you were very helpful.
