Correct Answer

Explanation

To express the product of 0.00043 and 2000 in standard form, we first multiply the two numbers together:\[0.00043 \times 2000 = 860\]Now, we need to express 860 in standard form. To do this, we write 860 as a number between 1 and 10 multiplied by a power of 10. In this case, 860 can be written as 8.6 × 100, which is the same as 8.6 × 10².Therefore, the product of 0.00043 and 2000 in standard form is \(8.6 \times 10^2\).
