    Answer:y=-1/2

    Step-by-step explanation:

    125 = (1/25) ^ (y-1)

    5^3 = (5^ (-2)) ^ (y-1)

    5^3=5^ (-2 (y-1))

    The same base eliminate each other we then have

    3=-2 (y-1)

    3=-2y+2

    Collect like terms

    2y=2-3

    2y=-1

    Divide both sides by 2

    2y/2=-1/2

    y=-1/2
