Answer:
![24\sqrt[3]{x^(7)}](https://img.qammunity.org/2019/formulas/mathematics/high-school/pz9v5i326c0gpwihymypvv6kwg74koqcim.png)
Explanation:
The exponent rule that applies to products like this is ...
... (a^b)(a^c) = a^(b+c)
In your problem, this is
... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)
This fractional exponent translates to the root of a power:
... = (x^7)^(1/3)
In typeset form, it is ...
![\sqrt[3]{x^(7)}](https://img.qammunity.org/2019/formulas/mathematics/high-school/fiu0gay6bub5l7s7q39m6o1nikainystus.png)
You have already figured correctly that the coefficient is 3·8 = 24.
