Answer
The simplified expression is 2000.
Solution
To simplify the expression, first evaluate 9 × 10^3. Since 10^3 = 1000, we have:
9 × 1000 = 9000.
Now subtract 7000 from 9000:
9000 − 7000 = 2000.
Thus, the simplified expression is 2000.

Simplify this solution Bonus Knowledge
To simplify \( 9 \times 10^{3} - 7000 \), first, we can convert \( 9 \times 10^{3} \) into a standard number. This equals 9000. So we have: \( 9000 - 7000 = 2000 \). Therefore, the simplified expression is \( 2000 \).
