    (A/B)^-1? whats the question?

    You have to get a positive exponent in the numerator and denominator first, right ?

    A ^ - 1 / B ^ - 1
    Can be written ?

    (1/A^1) / (1/B^1)

    Yes, A-1/B-1= (1/A)/(1/B). And to divide by a fraction, you invert and multiply: (1/A)(B/1)= B/A just as in the first response.
