Answer 2

It looks like you're asking for each of the given numbers to be expressed in scientific notation (also known as standard form), where a number is written as a product of a coefficient and a power of 10. Here's the conversion for each of the numbers you provided:

1. 80,000 = 8.0 × 10^4
2. 350,000 = 3.5 × 10^5
3. 105 = 1.05 × 10^2
4. 89.3 = 8.93 × 10^1
5. 0.56 = 5.6 × 10^-1
6. 0.0000023 = 2.3 × 10^-6
7. 0.0309 = 3.09 × 10^-2
8. 67 × 10^5 = 6.7 × 10^6
9. 345 × 10^-4 = 3.45 × 10^-2

Please note that in scientific notation, the coefficient should be between 1 and 10, and the power of 10 represents how many places the decimal point has been moved to create the original number.
