Introduction / Context:Pattern: write each digit’s square in order and concatenate. Example validates the rule for 176.
Given Data / Assumptions:
- 176 → (1^2)(7^2)(6^2) → 1, 49, 36 → 14936.
- Apply to 549 → (5^2)(4^2)(9^2).
Concept / Approach:Compute squares: 5^2=25, 4^2=16, 9^2=81. Concatenate in the same order → 251681.
Step-by-Step Solution:Square each digit.Concatenate preserving order.
Verification / Alternative check:Check digit boundaries: “25|16|81” → 251681.
Why Other Options Are Wrong:They permute the blocks or digits.
Common Pitfalls:Misordering blocks or squaring incorrectly.
Final Answer:251681.
