Ordering the following numbers, which number is the greatest: 6.5×10^3, 4.5×10^3, 1.95×103, 6.2×10^3?(1 point)

To compare these numbers, we need to first convert them all to standard form.

6.5×10^3 = 6500
4.5×10^3 = 4500
1.95×10^3 = 1950
6.2×10^3 = 6200

Now, we can order them from greatest to least:

1. 6200
2. 6500
3. 4500
4. 1950

Therefore, the greatest number is 6200.
