[tex] x^\frac{4}{3} x^ \frac{2}{3} [/tex]Lets get started :)
Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.
When multiplication occurs in the same base, we add the powers
[tex] x^\frac{4}{3} x^ \frac{2}{3} [/tex]
↓ (I am going to perform the problem separately and then give the final answer as the power to x)
[tex] \frac{4}{3} + \frac{2}{3} [/tex] = [tex] \frac{6}{3} = 2[/tex]
↓
x²
[tex](x^2)^ \frac{1}{3} [/tex]
The power of a power should be performed by multiplying the powers together.
2 x [tex] \frac{1}{3} [/tex] = [tex] \frac{2}{3} [/tex]
[tex] x^\frac{2}{3} [/tex]
Your final answer will be the second option
