Praxis 5003 Practice Test Practice Question
Which of the following is equal to 3*(4+2)^2 + 12*3 - 1*4?
Correct Answer: A
Rationale: To solve the expression 3*(4+2)^2 + 12*3 - 1*4, start by simplifying inside the parentheses: 4 + 2 equals 6. Then, calculate (6)^2, which is 36. Next, multiply by 3, resulting in 108. The term 12*3 equals 36, and subtracting 4 gives 32. Adding these results together: 108 + 36 - 4 equals 140, which matches option A.
Option B (140) miscalculates the final sum. Option C (356) and option D (2,492) are far too high, indicating a misunderstanding of the order of operations or arithmetic. Thus, option A accurately reflects the correct computation.
