I am not understanding this problem

3^-1x^4/3^3x^-7

The negative exponents is messing me up. could some one explan a easy why to do it.

I think you mean that you have 3 raised to a -1 power divided by 3^3. What you do with negative powers is just moved them up or down in the fraction to make the power positive.

so, you can move the 3 to the denominator as 3^1 power now combine the 1st power with the 3rd power and you will have 3^4 = 81.

You can move the x^-7 to the top of the fraction to get x^7 and you multiply time x^4/3 which means you add 7 and 4/3 to get the powe for x.
So would my answer be x^11/3^-4

the proble is simplify and write using positive exponents only:

3^-1x^4/
3^3x^-7
