Answer 3

To evaluate the expression, we'll perform the operations step by step:

Step 1: Square the first term (-5, 8)²: (-5, 8)² = (-5)² + 8² = 25 + 64 = 89

Step 2: Multiply the second term 14, 28 by (-5/7): 14, 28 * (-5/7) = 14, 28 * (-5) / 7 = (-71.4) / 7 = -10.2

Step 3: Subtract the result from Step 2 from the result of Step 1: 89 - (-10.2) = 89 + 10.2 = 99.2

Step 4: Subtract 30, 04 from the result of Step 3: 99.2 - 30.04 = 69.16

So, the final result of the expression is 69.16.
