Alice has the correct solution.
Aaron made a mistake by adding the exponents when multiplying same bases. The correct way to solve 7^3 x 7^9 is to add the exponents, which would give the correct solution of 7^12, as shown by Alice.
Alice and Aaron are working as a pair in math class. They decide to each answer the question asked and compare solutions.
Alice: 7^3 x 7^9 = 7^27
Aaron: 7^3 x 7^9 = 7^12
Who has the correct solution and what did the person do that missed it that was incorrect?
