We are asked to find what the expression n^(-6) times p^3 is when all exponents are written as positive.
Recall the property for negative exponents that tell us that a negative exponent means to flip the expression over the fraction line in the way shown below:
a^(-n) = 1 / (a^n)
So, we do that for the negative exponent of our case:
n^{-6} = 1 / n^6
which means that now n to the power 6 go in the denominator.
our final expression is then:
p^3 / n^6 (p to the power 3 divided by n to the power 6)
which agrees with the third answer of the list.
