    Answer:

    x = 0

    Step-by-step explanation:

    -[(3^x – 1)(5^x – 1)] + 1 = 1

    Subtract 1 form both sides

    -[(3^x – 1)(5^x – 1)] = 0

    Divide both sides by -1

    (3^x – 1)(5^x – 1) = 0

    Equate the factors to 0

    3^x – 1 = 0

    3^x = 1

    Use ln both sides

    ln(3^x) = ln(1)

    xln(3) = 0

    x = 0

    5^x – 1 = 0

    5^x = 1

    Use ln both sides

    ln(5^x) = ln(1)

    xln(5) = 0

    x = 0

    The only solution is x = 0
