The Correct Answer and Explanation is: The correct answer is 3³. This problem asks to simplify the expression 3⁻⁹ / 3⁻¹². To solve this, we use the properties of exponents, specifically the quotient rule for powers with the same base. The quotient rule of exponents states that when dividing two terms with the same base, you […]
Problem 2: Recall the expression we studied in class: 48/2(9 + 3), and consider the following calculations performed by a student to evaluate the expression: = 2 2(9 + 3) + 29 + 3) (9 + 3) (a) This student equated the original horizontal alignment with vertical alignment: 48/2(9 + 3) = 209 + 3
