Rosa, Roberto, Andrea, and Eno. Find an estimate for. Square root 10. Who has proposed the best solution?

To find an estimate for the square root of 10, let's consider the proposed solutions by each person:

1. Rosa: She suggests that the square root of 10 is approximately 3.
2. Roberto: He suggests that the square root of 10 is approximately 3.5.
3. Andrea: She suggests that the square root of 10 is approximately 3.2.
4. Eno: Eno has not provided a suggested solution for the square root of 10.

Based on the proposed solutions, it seems that Roberto has proposed the best solution with an estimate of 3.5. However, it's worth noting that none of these estimations are precise as the exact value of the square root of 10 is 3.16227766... (rounded to eight decimal places).
