    x=3 y=-2

    Step-by-step explanation:

    you must take the right part of the equation and express it as (something) ^1/6

    you know that the general formula is (a^b) ^c = a^ (b*c)

    and (ab) ^c = (a^c) * (b^c)

    so you must reach a situation where you express everything ^1/6

    a^ (1/2) = a^ (3/6) = (a^3) ^1/6

    b^ (-1/3) = b^ (-2/6) = (b^-2) ^1/6

    AND

    ((a^3) ^1/6) * ((b^-2) ^1/6) = (a^3*b^-2) ^1/6

    therefore

    x=3 and y=-2
