    Answer:

    5^{-3}

    Step-by-step explanation:

    Given the indicial expression

    (5^{-2})(5^{-1})

    First let us convert them to fraction;

    5^-2 = 1/5^2

    5^-2 = 1/25

    Also;

    5^-1 = 1/5^1

    5^-2 = 1/5

    Multiplying both fractions;

    (5^{-2})(5^{-1}) = 1/25 * 1/5

    (5^{-2})(5^{-1}) = 1/125

    (5^{-2})(5^{-1}) = 1/5^3

    1/5^3 = 5^{-3}

    Hence the required answer is 5^{-3}
