## Spring98 one year ago What is the value of https://cv-kettle-falls.brainhoney.com/Resource/30603643,0/Assets/75122_53df8565/01_08_17.gif

1. Nnesha

$\huge\rm \frac{ x^m }{ x^n }=x^{m-n}$when we divide same bases we should subtract their exponents

2. Spring98
3. Nnesha

how did you get that ?

4. Spring98

i don't know

5. Nnesha

subtract their exponents here is an example $\huge\rm \frac{ 2^3 }{ 2^2 } =2^{3-2}$

6. Spring98

it is 2

7. Nnesha

no $\huge\rm \frac{ 5^4 }{ 5^6 }=5^{4-6}=5^{??}$

8. Spring98

oh oops ya i did get that wrong .so the right answer is -2 right?

9. Nnesha

yes so $\huge\rm 5^{-2}$ now flip the fraction to get positive exponents

10. Spring98

how?

11. Nnesha

$\huge\rm x^{-m}=\frac{ 1 }{ x^m }$ when you flip the fraction sign of the exponents would change

12. Spring98

so the answer is supposed to be 1/81, 1/27, 1/9, or 1/3. those are the choice answers. which one would it be then?

13. Nnesha

is it 8 or 6 at the denominator ? sorry can't see ...

14. Spring98

?

15. Nnesha
16. Nnesha

17. Nnesha

$\huge\rm 5^{-2}$ flip the fraction to get positive exponents exxample $\huge\rm x^{-m}=\frac{ 1 }{ x^m }$ when you flip the fraction sign of the exponents would change

18. Spring98

they are right or else your anwer is wrong look again!

19. Nnesha

you should look at ur answer choices

20. Spring98

thats the answer choices they give me. And to tell you the truth i believe them more than you so don't tell me what to do.

21. Nnesha

you have to be make sure tht you type it correctly. do you think i'm telling u the wrong answer ?

22. Nnesha

i was helping you so i have to tell you the post the right stuff. they can be wrong you should believe on mathematically concepts
