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
Who has the correct solution and what did the person do that missed it that was incorrect?
1 answer
Aaron has the correct solution. Alice's answer, 7^3 x 7^9 = 7^27, is incorrect. The correct solution should be 7^3 x 7^9 = 7^(3+9) = 7^12. Alice incorrectly added the exponents together instead of multiplying them.
