Answer:
3 x 3 x 3 x 3 x 3 x 3 x 3 = 2,187
(or 3 x 7 = 2,187)
2,187 x 9 = 19,683
Explanation:
The little seven next to the three is a exponent, that means there is the amount of threes as the exponent. Find out what 3 x 7 is. You should have gotten 2,187. Then multiply that answer that you got with the number you are multiplying with (9). You should get your answer 19,683.
