Question 9

Javier simplified the expression below. Find and describe the three mistakes he made.

Revolt · Accepted Answer

Javier made three primary mistakes in his simplification: 1. In the third step, he did not raise the coefficients (5 and 20) to the third power as required by the power of a product rule. 2. In the denominator, he incorrectly raised x to the third power and got x^4 (likely by adding the exponents 1 and 3) instead of x^3. 3. In the final step, he divided the exponents (24 / 4 = 6) instead of using the quotient of powers property, which requires subtracting the exponents (24 - 4 = 20).

Question 10

Which of the following did you include in your response?

Revolt · Accepted Answer

Javier did not raise the coefficients to the third power; When Javier raised [image 1] to the third power, he wrote that [image 2] , but it equals [image 3] .; In the last step, Javier divided the exponents. He should have used the quotient of powers property and subtracted them.
