$\displaystyle (243)^\frac{1}{5}+\sqrt[6]{64}$

$\displaystyle (3^5)^\frac{1}{5}+\sqrt[6]{2^6}=3+2=5$

Let me just help explain earboth's response.

The meaning of $\displaystyle 16^{\frac{1}{4}}$ means, the same as $\displaystyle \sqrt[4]{16}$ and that means find a number when mutiplied 4 times gives 16, thus,

$\displaystyle 16^{\frac{1}{4}}=2$
