    Are -m and n exponents?

    \(\Large p^{-m} \cdot p^n\)

    If so, then to multiply powers with the same base, give the same base and add the exponents.

    The rule is: \(\Large a^m \cdot a^n = a^{m+n} \)

    You didn't post the choices, so I don't know if b is correct.

    You need to add the exponents. The exponents are -m and n. The sum of -m and n is: -m + n The answer is: \(\large p^{-m + n} \)

    Correct. In choice b, they multiplied the exponents. That is not correct for this problem.
