8. UsukiDoll

I believe you are getting $\LARGE 8^3$ confused with $\LARGE 8^{\frac{1}{3}}$

9. welshfella

512 is the CUBE of 8 8*8*8

10. UsukiDoll

yes @welshfella is correct.. 512 is 8 to the third power I'm asking cube root of 8. different.

11. welshfella

you need to find x where x*x*x = 8

12. welshfella

what number when multiplied by itself as above gives 8

13. anonymous

2

14. anonymous

2*2*2

15. UsukiDoll

yes because the cube root of 8 is 2 2^3 = 8 2 x 2 x 2 = 8 8=8

16. welshfella

right

17. anonymous

so the answer is 8? Really that simple?

18. UsukiDoll

the answer is 2 cube root of 8 is 2
