    The answer is 1/9.

    Step-by-step explanation:

    Using the equation a-b=2, we can solve that a = 2+b.

    We can then substitute that into the expression given to get 3^b/3^ (2+b).

    Since they have the same base, we can subtract the exponents from the numerator and denominator to get 3^ (b-2-b) which simplifies to 3^-2.

    3^-2 is simply 1/9.

    using laws of exponents ...

    m^a/m^b = m^a-b

    therefore,

    3^b/3^a = 3^b-a

    => 3^-2/

    => 1/3^2

    => 1/9
