What are the numbers represented in scientific notation?

To compare these numbers, we need to align them by their scientific notation.

1. 2.92 × 10^−5 = 0.0000292
2. 7.3 × 10^−10 = 0.00000000073
3. 5 × 10^4 = 50000
4. 4 × 10^5 = 400000
5. 4 × 10^0 = 4
6. 4 × 10^4 = 40000

### Comparison:

– The smallest number is 7.3 × 10^−10.

– The next is 2.92 × 10^−5.

– Then 4 × 10^0 = 4.
– Followed by 4 × 10^4 = 40000.
– Next is 5 × 10^4 = 50000.
– The largest is 4 × 10^5 = 400000.

### Summary:

The order from smallest to largest is:
7.3 × 10^−10 < 2.92 × 10^−5 < 4 < 4 × 10^4 < 5 × 10^4 < 4 × 10^5.
