## anonymous one year ago I need help will fan+medal?!?!?!?!

1. anonymous

simplify $\sqrt[3]{7}/\sqrt[5]{7}$

2. anonymous

A. 7 to the power of 1 over 5 B. 7 to the power of 8 over 15 C. 7 to the power of 5 over 3 D. 7 to the power of 2 over 15

3. anonymous

@Nasa7 CAN U HELP PLZ

4. anonymous

@rock_mit182 do u know how to simplify this?

5. Anguyennn

first question would be 1 because they are both the same and when you divide them together it would be 1

6. anonymous

i need it simplified though not the answer

@Queli what did you get ?

9. anonymous

Im not sure..

10. rock_mit182

keep in mind in our case: a = 7

11. rock_mit182

$7^{2/3}$ and $7^{2/5}$

14. rock_mit182

you were close enough, try again. keep in mind what i told you about : $7 = 7^{1}$

15. anonymous

$7^{1/3} and 7^{1/5}$ so the answer would be d right

16. rock_mit182

$\frac{ 7^{\frac{ 1 }{ 3 }} }{ 7^{\frac{ 1 }{ 5 }} } = 7 ^{\frac{ 1 }{ 3 }}* 7\frac{- 1 }{ 5 }$

17. rock_mit182

WHisch is the same as: $=7^{\frac{ 1 }{ 3 }-\frac{ 1 }{ 5 }}$

18. rock_mit182

can you solve this by your own now ?

19. rock_mit182

1/3 - 1/5 ?

20. rock_mit182

7 to the power of .... ?

21. anonymous

the common denominator would be 15 so 5/15-3/15=2/15

22. rock_mit182

yeah :)

23. rock_mit182

nice work

24. rock_mit182

that's all my friend

25. anonymous
