Arrange these numbers in increasing order: 216,000,000, 2.2 * 10 to the 3rd power, 3.1 * 10 to the 7th power, 310,000

216,000,000

2.2 * 10 to the 3rd power = 2.2 * 10^3 = 2,200

3.1 * 10 to the 7th power = 3.1 * 10^7 = 31,000,000

310,000

Increasing order:

2,200, 310,000, 216,000,000, 31,000,000

So increasing order with original numbers:

2.2 * 10 to the 3rd power, 310,000, 216,000,000, 3.1 * 10 to the 7th power
