Answer:
![x^{8/3}](https://tex.z-dn.net/?f=x%5E%7B8%2F3%7D)
Step-by-step explanation:
when taking the radical of a number its really just a fractioned exponent for example
= ![x^{1/2}](https://tex.z-dn.net/?f=x%5E%7B1%2F2%7D)
This is because in the radical the x has an exponent of 1 and since its the square root the radical is to the 2nd so you take the exponent of the X and put that of the what ever kind of radial you have such as a square root third root fourth root and so on...
in your case you would take X's exponent of 8 and since your taking the cube root would put the 8 over the 3.
hope that helped
Answer:
