Answer 2

To solve this expression step by step, 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). In this case, there are no exponents or square roots, so we can start with the parentheses and then proceed with multiplication and division from left to right.

Here's the expression solved step by step:

1. Inside the first set of parentheses: (13 - 9.5) / 3.8 = 3.5 / 3.8 ≈ 0.92105263158 (rounded to 11 decimal places)

2. Now, the expression becomes: 0.92105263158 × 0.3 (1.3 × 2.8 + 1) / 0.

3. Inside the second set of parentheses: 1.3 × 2.8 + 1 = 3.64

4. Continuing with the expression: 0.92105263158 × 0.3 × 3.64 / 0.

5. Now, perform the multiplication: 0.92105263158 × 0.3 × 3.64 = 1.00605263158

6. Finally, we have: 1.00605263158 / 0.

Division by zero is undefined in mathematics. Therefore, the final result of this expression is undefined (or "∞" to represent infinity), as you cannot divide by zero.
