Responses

1.429 × 10−5
1.429 times 10 Superscript negative 5 Baseline

1.429 × 10−3
1.429 times 10 Superscript negative 3 Baseline

1.429 × 10−6
1.429 times 10 Superscript negative 6 Baseline

4.129 × 10−4

Answer 1

To determine which number is higher than \( 1.429 \times 10^{-4} \), we can compare each of the given options.

1. **\( 1.429 \times 10^{-5} \)**
- \( 1.429 \times 10^{-5} = 0.00001429 \)
- This is lower than \( 1.429 \times 10^{-4} = 0.0001429 \).

2. **\( 1.429 \times 10^{-3} \)**
- \( 1.429 \times 10^{-3} = 0.001429 \)
- This is higher than \( 1.429 \times 10^{-4} \).

3. **\( 1.429 \times 10^{-6} \)**
- \( 1.429 \times 10^{-6} = 0.000001429 \)
- This is lower than \( 1.429 \times 10^{-4} \).

4. **\( 4.129 \times 10^{-4} \)**
- \( 4.129 \times 10^{-4} = 0.0004129 \)
- This is also higher than \( 1.429 \times 10^{-4} \).

So, the numbers that are higher than \( 1.429 \times 10^{-4} \) are:

- \( 1.429 \times 10^{-3} \)
- \( 4.129 \times 10^{-4} \)

Both of these options are correct responses.
