$\displaystyle 3\left(4^{\frac{4}{3}} + 3^{\frac{4}{3}}\right)$

that's as far as you can go.

$\displaystyle 3\left(4^{\frac{4}{3}} + 3^{\frac{4}{3}}\right)$

or
did u mean my last answer before question mark is accepted??

4. I meant what you arrived at at your last step ...

$\displaystyle \frac{3}{4}\left(4^{\frac{4}{3}} + 3^{\frac{4}{3}}\right)$

forgot the denominator of 4 under the leading 3

$\displaystyle 4^{\frac{4}{3}} + 3^{\frac{4}{3}}$ cannot be simplified further
