## kirk.freedman 2 years ago What is the solution of the equation?

1. kirk.freedman

2. kirk.freedman

I would like help on how to do this problem please.

3. hartnn

first isolate $$\sqrt[5]{(x+3)^3}$$ can u ?

4. kirk.freedman

No, I'm not sure how you would do that

5. hartnn

subtract 3 on both sides, what u get ?

6. kirk.freedman

oh i see, you get the same on the right minus the 3 and it = 24

7. kirk.freedman

left side*

8. kirk.freedman

9. hartnn

yes, now divide by 3 on both sides, what u get ?

10. kirk.freedman

|dw:1356996206975:dw|

11. hartnn

right, now raise 5th power on both sides, can u ?

13. xkylex

thx

14. hartnn

i think you should keep that as 8^5 only.

15. kirk.freedman

oh ok, now i distribute the ^2 on the left?

16. kirk.freedman

*^3

17. hartnn

now, write 8=2^3 and take cube root on both sides.

18. hartnn

need help with this? i think you try once...

19. kirk.freedman

I'm sorry, you lost me there

20. kirk.freedman

No, I just have no idea, can you draw this step for me please?

21. hartnn

|dw:1356996503357:dw| |dw:1356996534417:dw| got this ?

22. kirk.freedman

Ohhh, yeah I get it now

23. hartnn

|dw:1356996601632:dw|

24. hartnn

ok, can u find x now ??

25. kirk.freedman

30?

26. hartnn

x+2 =2^5=32 x=32-2=30 yes! correct :)

27. hartnn

@xkylex did u get all of this? any doubts ?

28. kirk.freedman
