Understanding the Problem
To solve the expression √785 + √729.50, we need to approximate the square roots of both numbers.
Approximation of √785
- √785 is close to √784, which is exactly 28 (since 28 x 28 = 784).
- Thus, we can estimate √785 to be slightly more than 28, approximately around 28.03.
Approximation of √729.50
- √729 is exactly 27 (since 27 x 27 = 729).
- Since 729.50 is slightly greater than 729, we can estimate √729.50 to be slightly more than 27, approximately around 27.01.
Adding the Approximations
Now, we will add the approximated values:
- √785 ≈ 28.03
- √729.50 ≈ 27.01
So,
- 28.03 + 27.01 = 55.04
Conclusion
Rounding off 55.04 gives us approximately 55. Therefore, the answer to the equation √785 + √729.50 is closest to option 'B', which is 55.
This method of approximation allows us to quickly assess the problem without needing to calculate the exact square roots.
