I am interpreting your question as 2^(2/3)*6^(1/3). The answer is 2*3^(1/3)=2root(3)(3).

Explanation:

Notice that (ab)^c=a^c*b^c. We can rewrite 6^(1/3)as 2^(1/3)*3^(1/3).

The question thus becomes 2^(2/3)*2^(1/3)*3^(1/3). However, a^b*a^c=a^(b+c). We can rewrite 2^(2/3)*2^(1/3) as 2^(2/3+1/3)=2^1=2.

The final answer is 2*3^(1/3). We can also write this using radical form: 2root(3)(3)
