1. The problem is to convert the number 2000 to 2 significant figures. 2. Significant figures are the digits in a number that carry meaning contributing to its precision. 3. The number 2000 has one significant figure if written as is, because the trailing zeros are not counted without a decimal point. 4. To express 2000 with 2 significant figures, we need to keep the first two non-zero digits and round accordingly. 5. The first two significant digits in 2000 are "2" and "0" (from the thousands and hundreds place). 6. Since the number is exactly 2000, writing it with 2 significant figures means expressing it as $2.0 \times 10^{3}$. 7. Therefore, 2000 to 2 significant figures is $2.0 \times 10^{3}$.
