Why the answer is C, and why the others tempt you.
**The reasoning**
Start by solving for x:
- If 3x = 27, we need to find what power of 3 gives us 27
- Write 27 as a power of 3: 27 = 3³ (since 3 × 3 × 3 = 27)
- So 3x = 3³, which means x = 3
Now find x²:
- x² = 3² = 3 × 3 = **9**
Wait... the answer says 81? Let me recalculate. If x = 3, then x² = 9, not 81.
**Actually, there's an error here.** If the correct answer is truly 81, then either:
- The question should be "3^x = 27" (3 to the power x), OR
- The correct answer should be A) 9, not C) 81
Assuming the question meant **3^x = 27**: Then x = 3, and x² = 9. ✓
**Why the wrong options tempt you**
Students confuse x with x², or mix up the original value (27) with the final answer.
**Quick takeaway**
Always solve for x FIRST, then square that result separately — don't skip steps or you'll square the wrong number!
