Question

The density of oxygen is about 1.429x10^-4 grams per liter. Which number is higher than 1.429x10^-4?

A. 4.129 x 10^-4
B. 1.429 x 10^-6
C. 1.429 x 10^-3

Answer 1

To determine which numbers are higher than \(1.429 \times 10^{-4}\), we can compare them directly.

1. **With scientific notation, it helps to express them in the same exponent.**
- \(1.429 \times 10^{-4}\) is already in the form we want to compare against.

Now let's compare the options:

- **A. \(4.129 \times 10^{-4}\)**:
- Since \(4.129 > 1.429\), this value is greater than \(1.429 \times 10^{-4}\).

- **B. \(1.429 \times 10^{-6}\)**:
- The exponent \(-6\) is less than \(-4\), meaning this number is smaller than \(1.429 \times 10^{-4}\).

- **C. \(1.429 \times 10^{-3}\)**:
- The exponent \(-3\) is greater than \(-4\), hence this value is also greater than \(1.429 \times 10^{-4}\).

**Conclusion:** The numbers that are higher than \(1.429 \times 10^{-4}\) are **A** and **C**:

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