does it look like this $\sqrt[3]{27^{2}}$

well a cubed root is equal to an exponent of (1/3) and since its squared it will be 27^(2/3)

captaincook maybe great, but I think there is more to be done ;) $\sqrt[3]{27^2}=(\sqrt[3]{27})^2=(\sqrt[3]{3^3})^2=3^2=9$This is what I would call simplifying. Writing it as 27^(2/3) just changes notation...

thank you for the concern. i misspoke, i actually needed to change the notation not simplify the equation.
