Question

Which expressions are equal to 11×10^3 ? Select all that apply. (1 point) Responses 11×100 11 × 100 11,000 11 , 000 11×10×10×10 11 × 10 × 10 × 10 33,000 33 , 000 11×11×11 11 × 11 × 11

Answer 1

To determine which expressions are equal to \( 11 \times 10^3 \), let's evaluate \( 11 \times 10^3 \):

\[ 11 \times 10^3 = 11 \times 1000 = 11000 \]

Now, let's check each response:

1. **11×100** → \( 11 \times 100 = 1100 \) (Not equal)
2. **11 × 100** → \( 11 \times 100 = 1100 \) (Not equal)
3. **11,000** → This matches \( 11000 \) (Equal)
4. **11 , 000** → This is the same as \( 11,000 \) (Equal)
5. **11×10×10×10** → \( 11 \times 10 \times 10 \times 10 = 11 \times 1000 = 11000 \) (Equal)
6. **11 × 10 × 10 × 10** → \( 11 \times 10 \times 10 \times 10 = 11 \times 1000 = 11000 \) (Equal)
7. **33,000** → \( 33,000 \) (Not equal)
8. **33 , 000** → This is the same as \( 33,000 \) (Not equal)
9. **11×11×11** → \( 11 \times 11 \times 11 = 1331 \) (Not equal)
10. **11 × 11 × 11** → \( 11 \times 11 \times 11 = 1331 \) (Not equal)

The expressions that are equal to \( 11 \times 10^3 \) are:

- 11,000
- 11 , 000
- 11×10×10×10
- 11 × 10 × 10 × 10
