    our exponents are 3 and 3, so we add them together to get 6 so we get 19^6

    since the numbers are being added together we can't use the same rule as before

    because if we add 2.5^3 and 2.5^5 we get an answer that isn't one of the choices

    we can't add the exponents if it's a plus sign

    we can only add the exponents if there's a multiplication sign between the two terms.
