The image contains two sections of mathematical exercises:

1. **Finding square roots**:
   - 625
   - 857
   - 925
   - 554
   - 780
   - 1045
   - 2030
   - 980
   - 458
   - 378

2. **Performing multiplications**:
   - 45897 × 879
   - 76593 × 976
   - 66759 × 453
   - 45678 × 678
   - 77889 × 889

I will first solve the square root problems, and then proceed with the multiplications.

### Square Roots:
- √625 = 25
- √857 ≈ 29.27
- √925 ≈ 30.41
- √554 ≈ 23.53
- √780 ≈ 27.93
- √1045 ≈ 32.34
- √2030 ≈ 45.05
- √980 ≈ 31.30
- √458 ≈ 21.40
- √378 ≈ 19.44

I will now calculate the multiplications.Here are the results for the multiplication problems:

- 45897 × 879 = 40,343,463
- 76593 × 976 = 74,754,768
- 66759 × 453 = 30,241,827
- 45678 × 678 = 30,969,684
- 77889 × 889 = 69,243,321

Would you like further details on any of these calculations?

Here are some related questions to expand your understanding:
1. How is the square root of a non-perfect square calculated?
2. What is the difference between approximating and finding an exact square root?
3. Can the square roots of large numbers always be simplified?
4. How can the distributive property help in multiplying large numbers?
5. What are some alternative methods to calculate square roots?

**Tip**: To check multiplication results quickly, use estimation or split the numbers into more manageable parts.
