1. **State the problem:** Evaluate $$\frac{(5 \times 10^{3}) \times (2 \times 10^{-3})}{7}$$ and express the answer in standard form rounded to 2 decimal places.
2. **Use the properties of exponents and multiplication:** When multiplying powers of 10, add the exponents.
3. **Calculate the numerator:**
$$ (5 \times 10^{3}) \times (2 \times 10^{-3}) = 5 \times 2 \times 10^{3 + (-3)} = 10 \times 10^{0} = 10 $$
4. **Write the fraction:**
$$ \frac{10}{7} $$
5. **Simplify the fraction:**
$$ \frac{\cancel{10}}{7} = \frac{10}{7} $$ (no common factors to cancel)
6. **Divide to get decimal form:**
$$ \frac{10}{7} \approx 1.428571... $$
7. **Round to 2 decimal places:**
$$ 1.43 $$
8. **Express in standard form:**
$$ 1.43 \times 10^{0} $$
**Final answer:** $$1.43$$
