Explanation:
We have the following expression:
![(\sqrt[3]{x^(2)} \sqrt[6]{x^(4)})^(-3)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/1p9pzhuv6fzusv8frh09z85f480s1abh7d.png)
Which can also be written as:
![(x^{(2)/(3)} x^{(4)/(6)})^(-3)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/m05vt4y52gb30t93iwxja1mes851l03y6u.png)
Since we have exponents with the same base
inside the parenthesis, we can sum both exponents:
![(x^{(4)/(3)})^(-3)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/u6vq1iqfs9fcoxpl3bzlbyoxsipunsr4va.png)
Now, we have to multiply the exponent out of the parenthesis with the inner exponent and have the following result:
