Describe the error Sadie made, and explain how to find the correct answer.

Revolt · Accepted Answer

Sadie did not factor a to the 7th power using the largest perfect square. Instead of using a^2 * a^5, she should have used a^6 * a^1. Because the square root of a^6 is a^3, the exponent on a outside the radical in the final answer should have been 3.
