    Hello,

    I'm gessing only but I hope that you would like to caculate this:
    (243)^\frac{1}{5}+\sqrt[6]{64}

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

    Greetings

    Let me just help explain earboth's response.
    The meaning of 16^{\frac{1}{4}} means, the same as \sqrt[4]{16} and that means find a number when mutiplied 4 times gives 16, thus,
    16^{\frac{1}{4}}=2
