Answer 2

To simplify the given expression, let's break it down step by step:

1. Evaluate the square roots:

   • √2 = 1.414
   • √28 = 5.292
   • √63 = 7.937
   • √7 = 2.646
   • √126 = 11.225

2. Substitute the square root values back into the expression: (3 * 1.414 - 2 * 5.292 + 4 * 7.937) * 2.646 - 11.225

3. Perform the multiplications and subtractions within parentheses: (4.242 - 10.584 + 31.748) * 2.646 - 11.225

4. Simplify further: (25.406) * 2.646 - 11.225

5. Perform the remaining multiplication and subtraction: 67.259 - 11.225

6. Calculate the final result: 56.034

Therefore, the value of the given expression is approximately 56.034.
