Correct Answer

B

Explanation

To evaluate the expression (2.813 x 10⁻³) * (1.063 / 5.637 x 10⁻²), you can follow these steps:First, calculate the products and divisions without considering the exponential notation:(2.813 * 1.063) / (5.637)Now, calculate the result:(2.990719) / (5.637) ≈ 0.5299Since the original numbers were in scientific notation, the final answer should be in scientific notation as well. To convert 0.5299 to scientific notation, you need to express it as a number between 1 and 10 multiplied by the appropriate power of 10. In this case, you would write it as:5.299 x 10⁻¹So, the final result is approximately 5.299 x 10
