    The equation to use here is 3^x = 81. You could start to try numbers, and you would realize that x = 4 weeks.

    Week 4

    Step-by-step explanation:

    The function we have is

    f (x) = 3ˣ

    If there are 81 players, this gives us

    81 = 3ˣ

    81 = 9 (9) = 3 (3) (3) (3); this gives us

    3 (3) (3) (3) = 3ˣ

    This means x = 4
