Let’s define these exponents first:
3^8 = 6,561
3^2 = 9
Now that we have the exponents simplified, our problem is a lot easier! Let’s divide now:
6,561 / 9 = 729
In terms of powers, 729 = 3^6 (or three to the sixth power).
Another way to arrive at this answer would simply be to subtract the exponents since we are under the rule of “same number, different exponents.” That would automatically leave us at 3^6, which equals 729.
D is the answer.
