To determine which number is higher than \(1.429 \times 10^{-4}\), we can compare each option:
- \(1.429 \times 10^{-6}\) (which is \(0.000001429\)) - This is smaller than \(1.429 \times 10^{-4}\).
- \(1.429 \times 10^{-3}\) (which is \(0.001429\)) - This is larger than \(1.429 \times 10^{-4}\).
- \(1.429 \times 10^{-5}\) (which is \(0.00001429\)) - This is smaller than \(1.429 \times 10^{-4}\).
- \(4.129 \times 10^{-4}\) (which is \(0.0004129\)) - This is larger than \(1.429 \times 10^{-4}\).
Therefore, the numbers that are higher than \(1.429 \times 10^{-4}\) are:
- \(1.429 \times 10^{-3}\)
- \(4.129 \times 10^{-4}\)
