    4

    Step-by-step explanation:

    This is a substitution question

    So we will have to substitute the value of x given into the given question

    f (x) = 8^x

    And x is given as 2/3

    So let's get to work

    8^2/3 which means that cube root of 8 then square the answer

    (3√8) ^2

    Cube root of 8 is 2

    So we will have to square 2 to get 4

    Therefore the final answer is 4
