Ordering the following numbers, which number is the greatest: 6.5×10^3, 4.5×10^3, 1.95×103, 6.2×10^3

Answer 1

If we disregard the exponential form and compare the numbers themselves, we have:
6.5 × 10^3 = 6500
4.5 × 10^3 = 4500
1.95 × 10^3 = 1950
6.2 × 10^3 = 6200

Arranging them in descending order, we get: 6500, 6200, 4500, 1950

Therefore, the greatest number is 6500, which corresponds to 6.5 × 10^3.
