Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). Here's the step-by-step solution for your expression:

1. First, evaluate the expression inside the parentheses: (2.04 + 4.26) = 6.30

2. Now, we have: 12.6 / 6.30 - 0.564 × 15

3. Next, perform the multiplication and division from left to right: 12.6 / 6.30 = 2

   Now the expression becomes: 2 - 0.564 × 15

4. Continue with the multiplication: 0.564 × 15 = 8.46

   Now the expression becomes: 2 - 8.46

5. Finally, perform the subtraction: 2 - 8.46 = -6.46

So, the final result of the expression is -6.46.
