This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Apply the laws of exponents
Prompt focus: Simplify the expression (2x squared) cubed.
Why the correct answer works
8x to the sixth power
Cubing each factor gives 2 cubed which is 8, and x squared cubed which is x to the sixth.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Raise each factor to the third power. Two cubed is 8, and x squared raised to the third power is x to the sixth, since exponents multiply. The result is 8x to the sixth power.
Simple analogy
Think of apply the laws of exponents like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
