## hrcheerlove one year ago 1. 8y 7 ÷ 4y 5 2. (18x 5 + 6x 4 - 12x 3) ÷ 6x 2 helppppp???

1. Outkast3r09

$\frac{x^n}{x^m}=x^{n-m}$

2. hrcheerlove

huh ?

3. Outkast3r09

so first take care of the constants, $\frac{8}{4}=$

4. hrcheerlove

2

5. Outkast3r09

then you have $\frac{y^7}{y^5}$ since they have the same base you can use the above property so $\frac{y^7}{y^5}=y^{7-5}$

6. Outkast3r09

so combine your constant and your variables to get $2y^{7-5}=2y^2$

7. hrcheerlove

$(18x ^{5}+6x ^{4}-12x ^{3})\div6x ^{2}$ is the q btw it didnt post the powers

8. Outkast3r09

the second equation you need to split everything up into their own fractions

9. hrcheerlove

same for the first one

10. hrcheerlove

I have no idea how to do this

11. Outkast3r09

so $\frac{18x^5+6x^4-12x^3}{6x^2}=\frac{18x^5}{6x^2}+\frac{6x^4}{6x^2}-\frac{12x^3}{6x^2}$

12. Outkast3r09

then do what we did in the first one

13. hrcheerlove

Still have no idea lol

Thanks guys
