    The possible value of k is 64

    Step-by-step explanation:

    Integers are whole numbers, example, 1, 2, 3, 4, 5, 6, 7, 8, 9, etc

    Given;

    k ^1/3 = integer and

    k ^1/2 = integer

    To solve this, we think of a number whose cube root (k ^1/3) is a whole number (integer) and square root (k ^1/2) is also a whole number (integer).

    This number is 64

    Check:

    (64) ^1/3 = 4 (4 is an integer)

    (64) ^1/2 = 8 (8 is an integer)

    Therefore, the possible value of k is 64
