    Is this what you mean ?

    [tex]\frac {0.0002} {0.0256} = \frac {(0.1)^2} {(0.4)^2} \frac {(0.1)^Y} {(0.2)^Y}[/tex]

    If so, then Y=3.

    2.0E-4/2.56E-2 = (0.1^2/0.4^2) * (0.1^x/0.2^x)

    x = 3

    Looks like you just made a small mistake somwhere.

    It all simplifies to 1/128=[2^(-y)]/16, and then 1/8=2^(-y), and further 8=2^y.

    Thus I agree with Nico, y=3.
