Answer:
2
Step-by-step explanation:
When given a fractional power, you want to try to see if the base has any power that can be used to simplify the power.
Since a^b/c =
![\sqrt[b]{ {a}^{c} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Bb%5D%7B%20%7Ba%7D%5E%7Bc%7D%20%7D%20)
8^1/3=
![\sqrt[3]{ {8}^{1} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%7B8%7D%5E%7B1%7D%20%7D%20)
8 times by it self it 8
cube root of 8 is three numbers that are the same and times by each other to give 8
2×2×2=8
