Aaron has the correct solution. Alice made a mistake by adding the exponents when multiplying the same base. The correct way to solve this problem is to add the exponents:
7^3 x 7^9 = 7^(3+9) = 7^12
Therefore, Aaron's solution of 7^3 x 7^9 = 7^12 is correct.
Alice and Aaron are working as a pair in math class. They decide to each answer the question asked and compare solutions. Their answers were as follows:
Alice: 7^3 x 7^9 = 7^27
Aaron: 7^3 x 7^9 = 7^12
they are not sure why they got two different answers. who has the correct solution and what did the person do that missed it that was incorrect?
