Detailed Explanation & Answer
Let's evaluate each expression:

1. (0.011)² = 0.000121
(1.1)² = 1.21
(0.01)² = 0.0001
So, (0.000121) / (1.21 × 0.0001) = 1.

2. (0.11)² = 0.0121
(1.1)² = 1.21
So, (0.0121) / (1.21) × 0.1 = 0.001.

3. (1.1)² = 1.21
(1)² = 1 and (0.01)² = 0.0001
So, 1.21 / (1 × 0.0001) = 12100.

4. (0.11)² = 0.0121
So, (0.0121) / (1 × 0.01) = 1.21.

Only Expression 1 evaluates to 1. 😄
आइए प्रत्येक अभिव्यक्ति का मूल्यांकन करें:

1. (0.011)² = 0.000121
(1.1)² = 1.21
(0.01)² = 0.0001
तो, (0.000121) / (1.21 × 0.0001) = 1।

2. (0.11)² = 0.0121
(1.1)² = 1.21
तो, (0.0121) / (1.21) × 0.1 = 0.001।

3. (1.1)² = 1.21
(1)² = 1 और (0.01)² = 0.0001
तो, 1.21 / (1 × 0.0001) = 12100।

4. (0.11)² = 0.0121
तो, (0.0121) / (1 × 0.01) = 1.21।

केवल अभिव्यक्ति 1 का मूल्य 1 है। 🙂
