## vivalakoda Group Title Help with exponents? one year ago one year ago

1. vivalakoda Group Title

x$(x^{4})^{3/5}$

yes...

3. vivalakoda Group Title

Ignore the first x.

power on power will be multiplied

5. vivalakoda Group Title

I do not understand?

4*3/5=12/5

7. Australopithecus Group Title

Use the rules $x^3 = x(x)x$ $(x^3)^3 = (x^3)(x^3)(x^3)$

8. Australopithecus Group Title

$(x^3)(x^3) = x^6$

9. vivalakoda Group Title

I'm confused because my answer choices aren't any thing I am getting, or anything like that. They have square roots

10. Australopithecus Group Title

$(x^3)^3 = (x^3)(x^3)(x^3) = x^9$ 3*3 = 9 3 + 3 + 3 = 9

11. Australopithecus Group Title

look at my example and think about it

see this (x^2)^2 will x^4 i multiplied 2 with 2 for getting answer.

13. vivalakoda Group Title

I understand that you add the exponents when multiplying exponents

14. Australopithecus Group Title

look at my example though, once you understand why it is true you will be able to solve your answer very easily

yes just multiply exponents.

16. Australopithecus Group Title

do you know how to multiply fractions? $\frac{3}{4}*5 = \frac{3}{4}(\frac{5}{1 }) = \frac{3*5}{4*1} = \frac{3*5}{4} = \frac{15}{4}$

17. vivalakoda Group Title

Why are you using 3/4?

18. Australopithecus Group Title

I'm showing you examples of fraction multiplication, I'm not going to solve your problem for you, but I will teach you how to solve it

19. vivalakoda Group Title

I know how to do all of that, though.

20. Australopithecus Group Title

21. Australopithecus Group Title

exactly?

22. vivalakoda Group Title

All of the answers I'm getting are far from right. I'm really not sure what exactly I'm doing wrong

23. Australopithecus Group Title

well can you show your work?

24. Australopithecus Group Title

I can look it over for you and tell you where you are going wrong

25. Australopithecus Group Title

there isn't any trick to this problem, when you have $(x^3)^3 = x^9$ $(x^2)^{1/2} = x^{2\frac{1}{2}} = x^1 = x$ $(x^5)^{3} = x^{5*3} = x^{15}$

26. Australopithecus Group Title

show me the answer you are getting

27. vivalakoda Group Title

$(x^{4})^{3/5}$ = $x^{4/1} * ^{3/5}$ = multiplied the fraction, got x^12/5 thenhad to put it ion radical form: $\sqrt[5]{x}^{12}$

28. vivalakoda Group Title

in*

29. vivalakoda Group Title

after that i am clueless

30. Australopithecus Group Title

looks right

31. vivalakoda Group Title

I know I'm on the right track. But I don't know what else to do, do I simplify the x^12?

32. Australopithecus Group Title
33. Australopithecus Group Title

you cant simplify 12/5

34. Australopithecus Group Title

Email your instructor it is obviously a mistake on the site

35. Australopithecus Group Title

In the future it might help to post the answer you got in the question.
