    Exponential form: F (x) = 3/125^x+1

    Original voltage: 3/125 of a volt

    The correct answer is:

    x³ = 27/125; and

    x = 3/5.

    Explanation:

    Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us

    x³.

    The current voltage is 27/125; this gives us the equation

    x³ = 27/125.

    To solve this, take the cubed root of both sides:

    ∛ (x³) = ∛ (27/125)

    x = (∛27) / (∛125)

    x = (∛ (3*3*3)) / (∛ (5*5*5))

    x = 3/5
