2.3 × 10−^10; 3.2 × 10−^10; 2.3 × 10−^12; 2.3 × 10^−8

Answer 1

To compare the numbers you've provided, we'll first convert all of them to a standard format that allows us to easily compare their magnitudes.

1. 2.3 × 10^-10 = 0.00000000023
2. 3.2 × 10^-10 = 0.00000000032
3. 2.3 × 10^-12 = 0.0000000000023
4. 2.3 × 10^-8 = 0.000000023

Now we can order them from the smallest to the largest:

1. 2.3 × 10^-12 = 0.0000000000023 (smallest)
2. 2.3 × 10^-10 = 0.00000000023
3. 3.2 × 10^-10 = 0.00000000032
4. 2.3 × 10^-8 = 0.000000023 (largest)

Thus, the order from smallest to largest is: 2.3 × 10^-12 < 2.3 × 10^-10 < 3.2 × 10^-10 < 2.3 × 10^-8.
