    Step-by-step explanation:

    If you mean

    27^4 - 9^5·3^9 = - 1161730026

    it has no factors of 5, so cannot be divisible by 25.

    __

    If you mean ...

    (27^4 - 9^5) / 3^9 = ((3^3) ^4 - (3^2) ^5) / 3^9 = 3^10 (3^2 - 1) / 3^9 = 3 (9-1) = 24

    it is not divisible by 25, either.
