What did the other two do wrong in their answers?
Emma completed the problem correctly.
Erin made an error by adding the exponents, rather than multiplying them. The correct answer should be 6^7.
Eden made an error by forgetting to add the exponents of 6. The correct answer should be 6^7, not 6^2.

Eden made an error by forgetting to add the exponents of 6. The correct answer should be 6^7, not 6^2.
Eden 6^2 x 6^5 = 6^7
what mistake did Eden make in their answer
what mistake did Eden make in their answer
Eden did not make a mistake in their answer. Eden correctly solved for the product of two powers with the same base by adding their exponents. Therefore, 6^2 x 6^5 = 6^7.
6^2 x 6^5 =
6^2 x 6^5 = 6^(2+5) = 6^7
Therefore, the answer is 6^7.
Therefore, the answer is 6^7.
